Subject [jira] [Created] (WHIRR-339) Allow to specify hbase-site.xml properties through cluster configuration file

Allow to specify hbase-site.xml properties through cluster configuration file

                 Key: WHIRR-339
                 URL: https://issues.apache.org/jira/browse/WHIRR-339
             Project: Whirr
          Issue Type: Improvement
          Components: service/hbase
            Reporter: Bruno Dumon

Currently the hbase-site.xml configuration is hardcoded in the configure(_cdh)_hbase.sh script.
This patch adds dynamic generation of hbase-site.xml, modelled after what is done for hadoop-(common|mapred|hdfs)-site.xml.

The user is able to specify custom properties in their cluster configuration, by prefixing
them with 'hbase-site.'

Default config is in whirr-hbase-default.properties. Compared to what was in configure_hbase.sh
before, I dropped the setting of "hbase-site.hbase.client.retries.number=100" because I'm
not sure we should divert from the HBase default there.

I left in the passing of the ZOOKEEPER_QUORUM to the configure script, as I figured people
using custom scripts might still want to have it (there's a PORT variable passed that doesn't
seem to be used either).

On a more general note, this patch has the same limitations as for Hadoop: running master
and regionserver on same node will not work as the configuration will be appended twice to
the same file, and running the restserver/thriftserver not together with regionserver or master
will fail due to missing hbase-site.xml. Solving this is a topic of its own.
