Hello!

I have started studied HBase and I'm having a problem when tried execute
some command on Hbase shell.
I configured my HBase on Standalone mode. I have started HBase without
troubles, any exception have been throwed. But when I tried execute command
for create a table, for example, the following exception was throwed:

12/06/21 02:36:07 ERROR zookeeper.RecoverableZooKeeper: ZooKeeper exists
failed after 3 retries
12/06/21 02:36:07 WARN zookeeper.ZKUtil: hconnection Unable to set watcher
on znode /hbase/master
org.apache.zookeeper.KeeperException$ConnectionLossException:
KeeperErrorCode = ConnectionLoss for /hbase/master
Sorry for my ignorance. But... What can I do for solve this problem?

Hi Guilherme,

         First of all I would like to suggest you to use Hbase atleast
in pseudo-distributed modeif you want to learn things properly, as in
stand alone mode it doesn't use the Hdfs. But this is just an advice.
Now coming back to your problem, have you added "hbase.rootdir"
property in your hbase-site.xml file???

Hi

Yes, I added this property. I'll follow your advice.
I'll configure the HBase in pseudo-distributed and try again.
If I have any troubles I shout for help... xD
Thanks for attention

Hi Mohammad

I configured in  pseudo-distributed mode and it's running fine. But I'll
back the old configuration and try simulate the problem again and get the
logs for understand what was happening

Guilherme
