Description

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.

Caused by: java.lang.NullPointerException
	at org.apache.crunch.io.hbase.RegionLocationTable.create(RegionLocationTable.java:63)
