Subject RE: 0.90.1 hbase-default.xml
Date Mon, 07 Mar 2011 23:32:56 GMT
Thanks -

So we are up and running, but on the web UI we see "You are currently running the HMaster
without HDFS append support enabled. This may result in data loss. Please see the HBase wiki
for details.". 

" To enable sync, first ensure that you have either compiled the 0.20-append branch from Apache,
or installed Cloudera's CDH3 "

we are running 0.20.3-dev...we didn't see this message before with hbase 0.20.6. Now we see
the message after upgrading to 0.90.1. Is this message reliable? Should I worry?

Did you replace the hadoop jar in the hbase lib? It's compatible but
it still requires the same jar (yeah... it's a mess at the moment
since the append branch doesn't have a release).

You might also want to consider using CDH3b4, which has a compatible
hadoop and hbase.
