我有一个单节点hadoop，并在我的ubuntu12.04上安装了hbase。现在我想在hbase上安装titan。我已经安装了hadoop-1.0.3、hbase-0.94.18和titan/hbase-0.4.2
我添加了一个用户mnit.my/usr/local/文件夹包含hadoop2、hbase2、titan2。首先使用命令bin/start-all.sh启动hadoop，然后使用命令bin/start-hbase.sh启动hbase。之后，当我做jps时，我发现如下：

mnit@aman:/usr/local$ jps
9921 DataNode
11386 HRegionServer
11041 HQuorumPeer
11537 Jps
11115 HMaster
10153 SecondaryNameNode
10252 JobTracker
9691 NameNode
10483 TaskTracker

现在我使用bin/gremlin.sh命令在titan2中启动gremlin.sh。我应用了以下命令

mnit@aman:/usr/local/titan2$ bin/gremlin.sh
gremlin> conf = new BaseConfiguration();
==>org.apache.commons.configuration.BaseConfiguration@19288c2
gremlin> conf.setProperty("storage.backend","hbase");
==>null
gremlin> conf.setProperty("storage.hostname","127.0.0.1");
==>null
gremlin> g = TitanFactory.open(conf);

当我搜索这个问题时，我发现有一个名为pom.xml的文件，但是我下载的titan不包含pom.xml。请告诉我这是否是pom.xml引起的问题。或者我做错了什么，或者有其他问题。
提前谢谢
zk在我的系统中由hbase管理。我在bin/hbase-env.sh中添加了以下行

export HBASE_MANAGES_ZK=true

my hbase-site.xml的内容如下：

<configuration>
    <property>
        <name>hbase.rootdir</name>
        <value>hdfs://localhost:54310/user/hbase</value>
