-Re: How to clear hbase data in zookeeper

There are a couple ways you can do this. The first is the small hammer
assuming ZK is using /hbase you can log into the ZK from a ZK node using
/usr/lib/zookeeper/bin/zkCli.sh once you are in the shell you can then
execute a rmr /hbase and this will remove all the HBase data except the id
of the ZK node. Please make sure HBase is shut down.
There is a REALLY big hammer, some may call is a sledge hammer but you
can delete the ZK data dir. Go to each ZK node and from the shell as root
execute a rm -rf /<path to zk data> I believe the default is
/var/lib/zookeeper/version-2. Again this is not recommended and you should
have both HBase and ZK shut down for this.
