[jira] [Commented] (DRILL-2085) Failed to propagate error

["Deneche A. Hakim (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-2085?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14393265#comment-14393265 ] 

Deneche A. Hakim commented on DRILL-2085:
-----------------------------------------

I reverted back my branch to {{git.commit.id.abbrev=3e33880}} and was able to reproduce the error. It seems that the server returns a first batch with NULL data which throws a NullPointerException in {{DrillCursor}}, this caused the query to be cancelled from the client side. For this specific case, it's not an error propagation problem because there was no failure on the server side "yet"
