Help - can't start master server for HBase (pseudo-distributed mode).
Hello,
I am trying to set up HBase at pseudo-distributed mode on my Macbook.
I've installed Hadoop 1.0.3 in pseudo-distributed mode and was able to
successfully start the nodes:
$ bin/start-all.sh
$ jps
1002 NameNode
1246 JobTracker
1453 Jps
1181 SecondaryNameNode
1335 TaskTracker
1091 DataNode
Then I installed HBase 0.94 and configured it at pseudo-distributed mode.
$ ./start-hbase.sh
$ jps
1684 Jps
1002 NameNode
1647 HRegionServer
1246 JobTracker
1553 HQuorumPeer
1181 SecondaryNameNode
1335 TaskTracker
1091 DataNode
I couldn't find the MasterServer running so I looked at the log file:
2012-09-11 14:35:05,892 INFO

Could anyone help me to figure out what I am missing? I tried to do
some google search but none of the "answers" there helped me.
Here are my config files:
hbase-site.xml

</property>
</configuration>
I've also tried ssh localhost and here is what I found on my shell:
$ ssh localhost
Last login: Tue Sep 11 14:22:37 2012 from localhost
$ ssh localhost -p 22
Last login: Tue Sep 11 14:41:17 2012 from localhost
$ ssh localhost -p 8020
ssh: connect to host localhost port 8020: Connection refused
thanks!

Your HDFS server is listening on a different port than the one you
configured in hbase-site (9000 != 8020).
