Subject [jira] [Commented] (FLINK-2443) The Gather-Sum-Apply Version of Connected Components fails with NPE
Date Fri, 31 Jul 2015 16:37:05 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14649443#comment-14649443 ] 

Vasia Kalavri commented on FLINK-2443:
--------------------------------------

It seems it's the join with the solution set that is failing.
It looks like {{CompactingHashTable}}'s {{getMatchFor()}} returns a null buildSideRecord. Could you confirm?
If that's the case, then setting the solution set unmanaged configuration flag might be a temporary workaround.
