[jira] [Commented] (DRILL-1619) count(boolean) always returns 'true'

    [ https://issues.apache.org/jira/browse/DRILL-1619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14200484#comment-14200484 ] 

Aman Sinha commented on DRILL-1619:
-----------------------------------

The error message is : 
+        throw new RuntimeException("Boolean type does not support aggregate functions");
But count(bool) is supported, so should this be something like : "Only COUNT aggregate function supported for Boolean type"

> count(boolean) always returns 'true'
