> -----------------------------------
>
> Key: HBASE-1946
> URL: https://issues.apache.org/jira/browse/HBASE-1946
> Project: Hadoop HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 0.20.1
> Environment: two centos 5.3 installations
> hmaster + regionserver at first and regionserver at second.
> zookeeper quorum consists of one machine and located at the same place as
> master.
> Reporter: Dmitriy Lyfar
> Fix For: 0.20.2, 0.21.0
>
> Attachments: HRegionServer.patch
>
>
> While starting hbase I get following exception:
> {quote}
> java.lang.NullPointerException
> at
> org.apache.hadoop.hbase.regionserver.HRegionServer.run(HRegionServer.java:459)
> at java.lang.Thread.run(Thread.java:619)
> {quote}
> in region server's log on the second machine whereas at first machine all
> going well.
> We've discussed with larsgeorge this problem at IRC channel and seems problem
> is in HRegionServer implementation.
> Patch which fixies that problem attached to this message, but it should be
> not a final variant, because I cannot stop hbase with this fix.
