Subject Re: Use of the test cluster in HBase
Date Tue, 12 Apr 2011 21:38:04 GMT
Thanks, I'm only seeing the error when I change the block size, either
via DFSClient.create or via the Configuration dfs.block.size property.

When I changed the log4j.properties to
'log4j.logger.org.apache.hadoop=WARN' I'm not seeing anything
additional in the output in the target/surefire-reports directory.
