echo Stopping Hbase
# First, use the stop-hbase.sh script provided by HBase. This does a more graceful
# shutdown than using our kill-java-service.sh script.
${HBASE_HOME}/bin/stop-hbase.sh

# Second, also do a harder shutdown in case there is anything that is not covered
# by the stop-hbase.sh script. Kill region server first, then hmaster, and zookeeper.
"$DIR"/kill-java-service.sh -c HRegionServer -c HMaster -c HQuorumPeer -s 2

# Clear up data so that zookeeper/hbase won't do recovery when it starts.
# TODO: is this still needed when using bin/stop-hbase.sh?
rm -rf /tmp/hbase-*

# HACK: Some jobs have seen the HBase master fail to initialize with mesages like:
# "Master startup cannot progress, in holding-pattern until region onlined."
# Anecdotally, removing the MasterProcWALs directory avoids the issue.
