This jira is a follow-up jira of HADOOP-10255. It brings in the HttpServer in branch-2.2 directly into branch-2 to restore the compatibility of HBase.
Rename HttpServer to HttpServer2 to retain older HttpServer in branch-2 for compatibility
FYI with the reswizzle of branch-2.3, I think this was missed. I just merged it to the new branch-2.3.
I have committed this change to branch-2. Thank you Haohui Mai. Thank you stack for testing and review.
HttpServer needs to be removed in branch-2 once HBase stops using it from Hadoop Common.
+1 for the patch.
I am going to commit these changes soon. stack, if you do any more tests or find issues, please comment on this jira. We can have a separate follow up.
Putting in place a hadoop-common jar made from the tip of branch-2.3 with these HADOOP-10255 and HADOOP-10292 applied works for me. I am cluster-challenged at the moment so this was standalone test only (I tried a hadoop-common jar w/o the patches and got ClassNotFound for HttpServer... as expected). I'd be +1 on commit of this and hadoop-10255 (Let me know if you want me commit them). I will try and cluster test more this evening if I get my cluster back to see if that alters anything but do not expect it too. Thanks.
Thanks stack for the help. Once you confirm that it is working, I will commit the change.
Haohui Mai I am on it now.
stack, can you please quickly verify that HADOOP-10255 and HADOOP-10292 solve the compatibility issue for HBase? Thanks.
Based on the discussion in HADOOP-10255 and HBASE-10336, here is the proposed fix for the compatibility issues for HBase:
