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.
