Can not access HBase Shell.

[Jason Huang]

Hello,

I am trying to set up HBase at pseudo-distributed mode on my Macbook.
I was able to installed hadoop and HBase and started the nodes.

$JPS
5417 TaskTracker
5083 NameNode
5761 HRegionServer
5658 HMaster
6015 Jps
5613 HQuorumPeer
5171 DataNode
5327 JobTracker
5262 SecondaryNameNode

However, when I tried ./hbase shell I got the following error:
Trace/BPT trap: 5

Loooking at the log from master server I found:
2012-09-13 18:33:46,842 DEBUG

I don't quite understand what this error is and how to fix it. Any
suggestions?  Thanks!
