Description

The other day, when starting HBase I got this error:

2010-04-23 09:38:14,847 ERROR org.apache.hadoop.hbase.master.HMaster: Failed to start master
org.apache.hadoop.hbase.util.FileSystemVersionException: File system needs to be upgraded. Run the '${HBASE_HOME}/bin/hbase migrate' script.
        at org.apache.hadoop.hbase.util.FSUtils.checkVersion(FSUtils.java:187)

I was puzzled until I realized, after adding extra debug statements in the code, that I forgot to properly set hbase.rootdir after re-deploying my dev environment. I think the message above was misleading and I'm proposing a trivial patch to make it a little bit better:

2010-04-23 09:48:29,000 ERROR org.apache.hadoop.hbase.master.HMaster: Failed to start master
org.apache.hadoop.hbase.util.FileSystemVersionException: File system needs to be upgraded.  You have version null and I want version 7.  Run the '${HBASE_HOME}/bin/hbase migrate' script.
