Issue in connecting titan with hbase

I am trying to connect titan(0.5.2) with hbase(0.98.6).

I have started both hadoop and hbase, my JPS command look like below,

25824 HRegionServer
24227 NameNode
24403 DataNode
25557 HQuorumPeer
24778 ResourceManager
28412 Jps
25630 HMaster
25007 NodeManager

hbase-site.xml:

<property>
    <name>hbase.zookeeper.property.clientPort</name>
    <value>2222</value>
</property>

titan-hbase.properties

storage.hostname=127.0.0.1
cache.db-cache = true
cache.db-cache-time = 180000
cache.db-cache-size = 0.5

I have started titan using ./titan.sh start ../conf/titan-hbase.properties this command. 

9841 RemoteMavenServer
20643 CassandraDaemon
9381 Main
29512 Jps
21132 Application
27278 Launcher
21071 Elasticsearch

and used gremlin console to connect,

gremlin> TitanFactory.build().set('storage.backend', 'hbase').set('storage.hostname', '127.0.0.1:2222').open()

But i am not getting any reponse from gremlin console for this command. No error or stacktrace. just not connecting. Can you help me out here, i am totally new to this titan with hbase.

This properties file worked for me with Titan 0.5.4 using g = TitanFactory.open('/tmp/titan.properties'):

storage.backend=hbase
storage.hostname=127.0.0.1
storage.hbase.ext.hbase.zookeeper.property.clientPort=2222
storage.hbase.table=graphtest

Using the same properties with the builder TitanFactory.build()... did not work though:

Unknown configuration element in namespace [root.storage.hbase.ext]: zookeeper

Keep in mind that Titan 0.5.2 is quite dated (released in Nov 2014), and it depends on TinkerPop 2.5.0 (released in Apr 2014). Titan and TinkerPop 2.x are no longer under active development.

You should consider moving on to JanusGraph, which is a fork of Titan, has an active and open community, and is keeping current with the latest releases of Apache TinkerPop 3.x.
