ZooKeeper available but no active master location found

Hi all,
I am a new developer of hadoop and at the moment I fighting against an issue in hbase.
Actually I wrote a mapreduce that should be able also to write data in hbase directly.
Unlucky with my installation on my virtual machine I get the following error:

INFO client.HConnectionManager$HConnectionImplementation: ZooKeeper available but no active master location found
13/02/28 14:27:23
INFO client.HConnectionManager$HConnectionImplementation: getMaster attempt 1 of 10 failed; retrying after sleep of 1008
org.apache.hadoop.hbase.MasterNotRunningException

Are you able to provide me some useful hints?
Thanks a lot in advance for your help

Can you please verify if your zookeeper is running? If your zookeeper is not running, hbase master can be started.

Actually Itried to execute start-hbase.sh to start HMaster and after that I got the following output:
32110 HRegionServer
2130 HMaster
2429 Jps
31728 HQuorumPeer

However after executing:

hbase shell
status

it gives the same error and if I use again jps command the HMaster disappeared.

Thanks a lot

Hi Larry,
this is the output of the command you suggested me:

[root@localhost ~]# $JAVA_HOME/bin/jps
32110 HRegionServer
32445 Jps
31728 HQuorumPeer

What could I do to start the HMaster. Consider that I running hadoop in standalone mode.
Thanks a lot

Hi, Raffaello

The error is self explained. org.apache.hadoop.hbase.MasterNotRunningException

Please try to run jps to see if hmaster is running on your hbase master machine.

Here is the jps:
$JAVA_HOME/bin/jps

Thanks

Larry
