Hi,
when we start 0.96 using bin/start-hbase.sh the following code is executed
distMode=`$bin/hbase --config "$HBASE_CONF_DIR"
org.apache.hadoop.hbase.util.HBaseConfTool hbase.cluster.distributed | head
-n 1`
if [ "$distMode" == 'false' ]
then
"$bin"/hbase-daemon.sh $commandToRun master $@
else
"$bin"/hbase-daemons.sh --config "${HBASE_CONF_DIR}" $commandToRun
zookeeper
"$bin"/hbase-daemon.sh --config "${HBASE_CONF_DIR}" $commandToRun master
"$bin"/hbase-daemons.sh --config "${HBASE_CONF_DIR}" \
--hosts "${HBASE_REGIONSERVERS}" $commandToRun regionserver
"$bin"/hbase-daemons.sh --config "${HBASE_CONF_DIR}" \
--hosts "${HBASE_BACKUP_MASTERS}" $commandToRun master-backup
fi
Why are we always starting the zookeeper server? It should not be started
if this property is set, right?
<property>
<name>hbase.cluster.distributed</name>
<value>true</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>
I have commented it for my needs, but I'm wondering if it's normal or not
to have it.
I have a ZK server external to HBase.
