EOF when version file is empty
------------------------------
Key: HBASE-3258
URL: https://issues.apache.org/jira/browse/HBASE-3258
Project: HBase
Issue Type: Bug
Reporter: Jean-Daniel Cryans
Assignee: Jean-Daniel Cryans
Priority: Blocker
Fix For: 0.90.0, 0.92.0
I somehow was able to get an empty hbase.version file on a test machine and
when I start HBase I see:
{noformat}
starting master, logging to
/data/jdcryans/git/hbase/bin/../logs/hbase-jdcryans-master-hbasedev.out
Exception in thread "master-hbasedev:60000" java.lang.NullPointerException
at
org.apache.hadoop.hbase.master.HMaster.stopServiceThreads(HMaster.java:559)
at org.apache.hadoop.hbase.master.HMaster.run(HMaster.java:286)
{noformat}
And in the master's log:
{noformat}

I thought that that kind of issue was solved a long time ago, but somehow it's
there again. I'll fix by handling the EOF and also will look at that ugly NPE.
