[jira] [Commented] (DRILL-4686) Aggregation query over HBase table
results in IllegalStateException: Failure while reading vector
[ https://issues.apache.org/jira/browse/DRILL-4686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15290605#comment-15290605 ]
Khurram Faraaz commented on DRILL-4686:
---------------------------------------
Removing the CONVERT_FROM(a.`v`.`e0`, 'UTF8') as k, from the project in the query returns results, we do not see the Exception.
