全分布式HBase启动后HMaster和HRegionServer自动消失

我在三台主机上配置Hadoop 2.2.0 和HBase 0.98.3 (其自带的hadoop common的jar包就是2.2.0版本的)，一台机器为Debian 7.5, 机器名为psyDebian，运行namenode和datanode，另外两台为centos 6.5, 名字分别为centos1和centos2，运行datanode。Hadoop的hdfs运行良好，但在其基础上运行HBase时，刚开始启动良好，但是过一会后HMaster和HRegionServer自动退出。一开始时主节点上jps是这样的：

        5416 NameNode
        5647 SecondaryNameNode
        5505 DataNode
        398 Jps
        32745 HMaster
        32670 HQuorumPeer

等了十几秒后，jps是这样：

        5416 NameNode
        5647 SecondaryNameNode
        5505 DataNode
        423 Jps
        32670 HQuorumPeer

从节点中的HRegionServer也是同样如此。
hbase-hadoop-master-psyDebian.log日志有错误，如下：

2014-07-16 09:57:01,061 WARN  [main-SendThread(centos1:2181)] zookeeper.ClientCnxn: Session 0x0 for server centos1/192.168.1.110:2181, unexpected error, closing socket connection and attempting reconnect

    ...

貌似是zookeeper有错误，但是我用的是hbase自带的，HBASE_MANAGES_ZK=true已经设置，而且HQuorumPeer进程一直在运行。

在hbase-hadoop-master-psyDebian.out中有个警告：

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/opt/hbase/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]

SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

hbase-hadoop-zookeeper-psyDebian.log中只重复如下信息：

2014-07-16 10:05:57,502 INFO  [WorkerReceiver[myid=0]] quorum.FastLeaderElection: Notification: 1 (n.leader), 0x0 (n.zxid), 0x26 (n.round), LEADING (n.state), 1 (n.sid), 0x0 (n.peerEPoch), LOOKING (my state)

在从节点中的hbase-hadoop-regionserver-centos1.log日志如下

2014-07-16 09:57:05,150 ERROR [main] regionserver.HRegionServerCommandLine: Region server exiting
java.lang.RuntimeException: HRegionServer Aborted

从节点hbase-hadoop-hbase-centos1.out居然报了找不到类的错误

Exception in thread "main" java.lang.NoClassDefFoundError: hbase
Caused by: java.lang.ClassNotFoundException: hbase

因为我是刚开始使用Hbase，不太了解源码，所以没法从源码级别找错误。我在网上寻找了四五天的答案，没找到有用的信息。三台机器时间已经同步，防火墙全部关闭，也反复删除临时文件重启多次，依旧HMaster和HRegionServer十几秒后退出。后面是我的关键配置文件：
