Subject [jira] [Commented] (PHOENIX-4366) Rebuilding a local index fails sometimes
Date Thu, 12 Apr 2018 00:24:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-4366?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16434758#comment-16434758
] 

James Taylor commented on PHOENIX-4366:
---------------------------------------

Yes, that looks right, [~elserj]. Sorry about that - I'm not able to compile the branch (due
to HBase dependency). I tried installing locally and that produced errors as well. I'll just
hold off on pushing anything to the branch until things get sorted out.

> We have a table created in 4.12 with the new column encoding scheme and with several
local indexes. Sometimes when we issue an ALTER INDEX ... REBUILD command, it fails with the

> This failure is intermittent, since usually we can run the command again and it will
succeed.
