Subject Re: hbase 0.20.0 Release Candidate 1 available for download
Date Wed, 05 Aug 2009 18:41:54 GMT

hey,

I'm having problems starting up this version at all.  

Here is what i've done so far:

1. changed data dir to a new location, and port for HDFS.  
2. formatted namenode
3. started dfs
4. setup zookeeper properties in hbase-site.xml
5. started hbase

it prints out normal output (starting master... starting zookeeper etc.). 
Any when i do a jps on master box i see this:

19581 HMaster
18114 SecondaryNameNode
19511 HQuorumPeer
17837 NameNode
19798 Jps
17974 DataNode

which is all correct as well.  the regionservers look good as well using
jps.   But when i try to access the master HBase UI... i get the following
the broswer:

HTTP ERROR: 500
Trying to contact region server null for region , row '', but failed after 3
attempts.
