NullPointerException in ClientScanner
-------------------------------------
Key: HBASE-1934
URL: https://issues.apache.org/jira/browse/HBASE-1934
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.20.1
Reporter: Daniel Ploeg
Fix For: 0.20.2, 0.21.0
The following stack trace was observed whilst loading a large volume of data
into Hbase:
Caused by: java.lang.NullPointerException
at org.apache.hadoop.hbase.client.HTable$ClientScanner.next(HTable.java:2008)
at
org.apache.hadoop.hbase.client.HTable$ClientScanner$1.hasNext(HTable.java:2089)
It appears that lastResult is initialized to be null, however in the exception
handling code there isn't any null checking before the field is accessed for
get row:
this.scan.setStartRow(this.lastResult.getRow());
There should be some additional null checking logic here.
