Assignee: Andrew Purtell
> 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
> Assignee: Andrew Purtell
> Fix For: 0.20.2, 0.21.0
>
> Attachments: HBASE-1934.patch
>
>
> 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.
