Exception while trying list tables in Hbase 0.20 alpha

[Saptarshi Guha <sa...@gmail.com>]

Hello,
I installed Hbase 0.20 alpha with 2 region servers and zoo.cfg has an
entry for the master(which is also a region)
I started it using hbase-start.sh

Yesterday from the hbase shell, i listed the tables and this worked.
Today after creating a table in another application(using java), i
went to the hbase shell and tried to list the tables but got this
exception
 WARN zookeeper.ZooKeeperWrapper: Failed to create /hbase:
org.apache.zookeeper.KeeperException$ConnectionLossException:
KeeperErrorCode = ConnectionLoss for /hbase
	at org.apache.zookeeper.KeeperException.create(KeeperException.java:90)
	at org.apache.zookeeper.KeeperException.create(KeeperException.java:42)


What should I do to remedy this?
I tried checking out 0.20 from the svn branch but ant fails with javax
class not found exception.

Any help would be appreciated
Regards
Saptarshi

Hi Saptarshi,

HBase should recover from WARNs like that. We'd need to see more information
around that to get full context.
Can you run your command again with DEBUG enabled and provide a full log?
