hbase installation problem
I just deployed hbase 0.2.1 to the existing hadoop 0.17.1.
13 machines, fully distributed
but I found I can't see the Web UI of hbase's master. (http://master:60010)
I checked the log, and master's log shows as follows
2008-10-30 00:56:54,296 INFO org.apache.hadoop.hbase.master.BaseScanner:
RegionManager.rootScanner scanning meta region {regionname: -ROOT-,,0,

has anyone met the same question before?

You can't reach the UI because HBase master didn't start (that's what the
log files says , at least).
>From my experience , it looks like a misconfigured conf file. If you'd post
it I might be able to help a little more.
Are you sure all the region servers conf file are updated to the specific IP
of the region server?
Vale et me ama
