[jira] [Commented] (CRUNCH-695) NullPointerException in RegionLocationTable

["Andrew Olson (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CRUNCH-695?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17066787#comment-17066787 ] 

Andrew Olson commented on CRUNCH-695:
-------------------------------------

Appears the region info may potentially be null as well (HBASE-10630) so we should check for that also.

> We saw this exception in processing jobs when Region Servers were abruptly aborting and restarting causing offline or in-transition regions. While there may be an underlying HBase client bug, the Crunch code should more gracefully handle this apparent possibility.
