> 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.
