Doesn't this JIRA be superseded by HIVE-5976 ?

I don't think this is superceded by HIVE-5976, but rather we have to figure out who one goes first and the other will have to update their patch. Since HIVE-5976 is a larger patch and will make this patch much smaller, I am inclined to let that one go first.

David Chen what are your thoughts?

Thanks for contributing this, Ashish Singh!

I agree with Brock Noland on this. Once HIVE-5976 goes in, then this patch will become much simpler since adding native support for Avro will no longer require the changes to the Hive grammar and parser.

Brock Noland and David Chen, thanks for reviewing the work.

Sounds good to me. I have to anyways address Brock Noland's review comments.

By the way, it may also be good to add a qfile test for Avro schema evolution over different partitions. I remember we have had to fix some issues related to schema evolution, such as HIVE-6835.

FYI, I also have a TypeInfo to Avro Schema converter in my patch for HIVE-7286 along with some unit tests for the converter. Feel free to go ahead and make use of it.

David Chen Thanks for the pointers here. I do have a test for avro over partitions, avro_partitioned_native.q.

I have addressed the reviews and updated RB with latest patch. Will attach latest patch here once I have rebased it over HIVE-5976.

Does anyone object to changing the summary of this ticket to "CREATE TABLE should support STORED AS AVRO"? The current description can be misinterpreted to mean that this patch is adding the AvroSerDe.

Would that mean with this patch we still need to specify the SerDe when creating an Avro table?

That change sounds good to me.

Jeremey, no I believe this is a metadata change only.

Updated patch after rebase.

Thanks, Ashish. I saw that you have a test for partitioned tables. Can you also include one that covers schema evolution, i.e. when the schema changes over partitions, such as the case in HIVE-6835?

Thanks for adding the qtest for schema evolution, Ashish!

Aside from some minor formatting comments, this looks good to me.

Tom White, Lars Francke, Brock Noland: Are you guys satisfied with the current version of the patch? If so I'll plan to +1 it and get it committed after another round of automated tests. Thanks.

All reviews on RB are addressed. Once I get a ship it there, I can post the patch here for automated tests.

Addressed review comments on RB.

Patch looks good. Ashish, thanks a lot for addressing all these minor comments. Ship it! (not a committer)

Looks good to me as well. +1 (also not a committer)

+1

this is an awesome contribution...

I have verified that the test failures do not appear to be caused by this patch.

• The TestMinimrCliDriver failure also fails on trunk
• The TestOrcHCatLoader failure is a known issue and also fails on trunk spuriously.
• I was not able to reproduce the TestCompactionTxnHandler or TestHiveServer2 failures on both trunk and this patch applied on trunk.

I think this patch is ready to be committed.

Yes, the failed tests are not related to this patch.

Committed to trunk. Thanks Ashish!

Thanks all for reviewing and committing.

This will need documentation when 0.14.0 gets released (with version note and link to this JIRA ticket):

• Avro SerDe (multiple sections)
• DDL – Create Table (syntax: list of values for file_format)
• DDL – Row Format, Storage Format, and SerDe

Great to see this committed. I cannot say enough how awesome this change is!

Lefty Leverenz thanks for looking at this. I am not sure how documentations are handled. Could you please help me understand what needs to be done for the documentation here.

Brock Noland thanks!

Ashish Singh, wikidoc updates are handled various ways. Sometimes the developer takes care of it, sometimes I write it up and ask for review, and occasionally someone else writes it up. I usually edit what others write, making sure version information is included and cross references get made.

• In this case, I think I could revise the DDL sections adequately but you would probably do a better job revising the Avro SerDe wiki, keeping in mind that the old information needs to remain for users of previous releases.

• If you don't want to do it yourself, or even if you do, a release note on this JIRA ticket would be an excellent start.

• If you have an in-house tech writer who could do the job, their contribution would be most welcome — my backlog of doc tasks is daunting, I'm just doing this as a retirement hobby, and it's summertime.

The links in my previous comment show where revisions should go. The Avro SerDe doc has several examples of CREATE TABLE — the simplest approach is to add a second example for each one, saying "In Hive 0.14.0 and later, this syntax can be used:" (or something similar). A general statement or discussion of the new syntax would be good too.

Since the 0.14.0 release is a few months away, the documentation could wait although it might be best done while still fresh in your mind. To gain write access to the wiki, follow the instructions here:

• About This Wiki

Lefty Leverenz Thanks for detailed info here.

I have updated the JIRA's release note and documentation on Avro's usage in Hive, https://cwiki.apache.org/confluence/display/Hive/AvroSerDe. Feel free to make it better.

Thanks Ashish, your doc changes look good. I'm just making a few minor edits.

This sentence in the Avro SerDe doc is out of date: "The AvroSerde has been built and tested against Hive 0.9.1 and Avro 1.5."

1. Can I change it to "tested against Hive 0.9.1 and later"?
2. What Avro versions have been tested? (Their latest is 1.7.7: http://avro.apache.org/releases.html.)

Ashish Singh, why did you outdent union1 to bytes1 in the examples? I aligned them with the rest of the data types, then indented all of them two more spaces to make STORED AS AVRO stand out – but if you wanted the outdent, please revert my changes or ask me to do it.

Also, your example in "Hive 0.14 and later versions" under "Creating Avro-backed Hive tables" is identical to the one you added to the code block in "All Hive versions" just before it – was that deliberate, or an editing artifact? It seems to me the Hive 0.14 example in "All Hive versions" isn't necessary, but I left it in for now.

Please review my changes, because I moved some information around.

• Avro SerDe

I added STORED AS AVRO to the DDL wikidoc:

• Create Table – see file_format (at the end of the syntax)

  file_format:
    : SEQUENCEFILE
    ...
    | AVRO       (Note: Only available starting with Hive 0.14.0)
  

• Row Format, Storage Format, and SerDe
  "Use STORED AS AVRO for Avro files in Hive 0.14.0 and later (see Avro SerDe)."

Lefty Leverenz thanks for taking a look at the changes I made. Based on your feedback I have made following changes.

• As Hive 0.14 uses Avro 1.7.5, updated Hive and Avro version text accordingly.
• Removed the Hive 0.14 example in "All Hive versions" under "Creating Avro-backed Hive tables".

Let me know if I missed out anything.

Looks good, thanks Ashish Singh.

But (ever the nitpicker) we probably need Hive versions matched with Avro versions, because the wiki covers all Hive versions. Does Hive 0.13 also use Avro 1.7.5? If the Avro version is somewhere in the code, I can compile a list of Avro versions for various Hive versions.

Of course, this is beyond the scope of the jira. So if it's more than a moment's work, we should raise a new issue.

(I should grep before asking, not after.) Here's what I've found in the released branches, starting with 0.9:

Hive 0.9 – ivy/libraries.properties:avro.version=1.5.3
Hive 0.10 – ivy/libraries.properties:avro.version=1.7.1
Hive 0.11 – ivy/libraries.properties:avro.version=1.7.1
Hive 0.12 – ivy/libraries.properties:avro.version=1.7.1
Hive 0.13 – pom.xml: <avro.version>1.7.5</avro.version>
Hive 0.13.1 – pom.xml: <avro.version>1.7.5</avro.version>

Documented here:

• Avro SerDe – Requirements

Shouldn't AVRO be added as a possible value for the hive.default.fileformat parameter in HiveConf.java?

• Configuration Properties – hive.default.fileformat

Lefty Leverenz Right. I'll book that into new issue.

Navis created HIVE-8591 "hive.default.fileformat should accept all formats described by StorageFormatDescriptor" which also deals with the values for hive.query.result.fileformat – thanks!

This has been fixed in 0.14 release. Please open new jira if you see any issues.
