• Type: Improvement
• Status: Resolved
• Priority: Minor
• Resolution: Fixed
• Fix Version/s: 3.0.0-alpha-1, 2.2.7, 2.3.4, 2.5.0, 2.4.1
• Component/s: integration tests
• Release Note: Added IntegrationTestImportTsv.generatedHFileFolder configuration property to override the default location in IntegrationTestImportTsv. Useful for running the integration test when HDFS Transparent Encryption is enabled.

Description

Currently IntegrationTestImportTsv is generating HFiles under the working directory of the hdfs user executing the tool, before bulkloading it into HBase.

Assuming you encrypt the HBase root directory within HDFS (using HDFS Transparent Encryption), you can bulkload HFiles only if they sit in the same encryption zone in HDFS as the HBase root directory itself.

When IntegrationTestImportTsv is executed against a real distributed cluster and the working directory of the current user (e.g. /user/hbase) is not in the same encryption zone as the HBase root directory (e.g. /hbase/data) then you will get an exception:

 

ERROR org.apache.hadoop.hbase.regionserver.HRegion: There was a partial failure due to IO when attempting to load d :
hdfs://mycluster/user/hbase/test-data/22d8460d-04cc-e032-88ca-2cc20a7dd01c/IntegrationTestImportTsv/hfiles/d/74655e3f8da142cb94bc31b64f0475cc
org.apache.hadoop.ipc.RemoteException(java.io.IOException): /user/hbase/test-data/22d8460d-04cc-e032-88ca-2cc20a7dd01c/IntegrationTestImportTsv/hfiles/d/74655e3f8da142cb94bc31b64f0475cc can't be moved into an encryption zone.

 

In this ticket I make it configurable where the IntegrationTestImportTsv generates the HFiles. From now, one can execute this integration test on HDFS Transparent Encryption enabled clusters, like:

./bin/hbase org.apache.hadoop.hbase.mapreduce.IntegrationTestImportTsv -D IntegrationTestImportTsv.generatedHFileFolder=/<my hbase encryption zone path>/testdata
