Pseudo distributed mode in LocalHBaseCluster
--------------------------------------------
Key: HBASE-1511
URL: https://issues.apache.org/jira/browse/HBASE-1511
Project: Hadoop HBase
Issue Type: Improvement
Affects Versions: 0.19.3
Reporter: Evgeny Ryabitskiy
Priority: Minor
Fix For: 0.21.0
After changes to config and adding of parameter:
{code}
<property>
<name>hbase.cluster.distributed</name>
<value>false</value>
<description>The mode the cluster will be in. Possible values are
false: standalone and pseudo-distributed setups with managed Zookeeper
true: fully-distributed with unmanaged Zookeeper Quorum (see hbase-env.sh)
</description>
</property>
{code}
running HBase in pseudo destr mode become not so easy
I wish to have some option in LocalHBaseCluster for pseudo destr mode where I
wish to have:
* separate processes for Master and HRSs
* ability to dynamically change HRS number in cluster
* managed ZK cluster (like it is in local mode now)
* managed small local HDFS cluster
I think it is very useful for testing, debugging and for user experience with
HBase, who want to try something close to real HBase not some emulation in
standalone mode.
