Subject [jira] [Commented] (DRILL-2833) Exception on select * from INFORMATION_SCHEMA.COLUMNS
Date Fri, 24 Apr 2015 17:29:38 GMT

    [ https://issues.apache.org/jira/browse/DRILL-2833?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14511380#comment-14511380
] 

Victoria Markman commented on DRILL-2833:
-----------------------------------------

Daniel,

I have a situation where HBase plugin is enabled, but not installed. In one case I got an
exception (can't reproduce it again for some reason).
The other behavior was the hang when you are trying to select from INFORMATION_SCHEMA.COLUMNS.

Vicky.
