Hi,
I am trying to setup HBase on a single Windows Vista machine by
following the instructions mentioned here :
http://hbase.apache.org/docs/current/cygwin.html#Introduction
I see the HBase server jvm starting up and listening to the default port of
60000.
But when I launch a hbase shell (bin/hbase shell) and try a list command
(list), I get the following error:
*NativeException: org.apache.hadoop.hbase.MasterNotRunningException: null *
I checked the hbase master logs, and see the following exception that I
guess could be the problem
2010-12-02 19:34:11,809 WARN

<property>
<name>hbase.zookeeper.quorum</name>
<value>127.0.0.1</value>
</description>
</property>
This doesn't seem to be the case, and I see *no java process listening on
port 2181*
I also get the following message while starting hbase
*: hostname nor servname provided, or not known*
I am using HBase version 0.20.6
Any suggestions / pointers would be of great help! I am open to trying out
any suggestions.
Thanks
Vijay
