Bruno Dumon commented on WHIRR-334:
-----------------------------------

I tried to launch a CDH hbase cluster on EC2 using this patch, and I had the 
opposite problem: the master was not running, the region servers were running.

The master seemed to have exited because of this:

{noformat}
2011-07-14 15:48:26,912 WARN org.apache.hadoop.hdfs.DFSClient: Could not get 
block locations. Source file "/hbase/hbase.version" - Aborting...
2011-07-14 15:48:26,913 FATAL org.apache.hadoop.hbase.master.HMaster: Unhandled 
exception. Starting shutdown.

        at 
org.apache.hadoop.hdfs.server.namenode.NameNode.addBlock(NameNode.java:649)
{noformat}

I had the same problem over at WHIRR-240, but there the master survived this 
(possibly due to improved handling in newer HBase, or maybe due to timing 
differences).

Also strange was that all hadoop Java processes (datanode, tasktracker) 
appeared double, as if they were started twice.

I'll look some further into this tomorrow and will report back.

> I've updated the cdh services scripts and ZooKeeperClusterActionHandler.java 
> to properly work with CDH3 when setting up an HBase cluster. Tested multiple 
> times with 1 master + 1 region and also 1 master + 5 region on EC2.
> The only issue I ran into was previously documented in 
> https://issues.apache.org/jira/browse/HBASE-1960 where the HBase Master shuts 
> down after only one attempt to access DFS. This is something that should be 
> addressed by the HBase team or a fix integrated by Cloudera into CDH.
