zookeeper启动错误 transaction type: 2 error: KeeperErrorCode = NoNode for /hbase

　　hbase伪分布式，与zookeeper同一台机器的时候，运行一段时间，启动zookeeper的时候，日志中有如下错误，导致无法启动zookeeper



java.io.IOException: Failed to process transaction type: 2 error: KeeperErrorCode = NoNode for /hbase/unassigned

　　由于是伪分布式，zookeeper集成在hbase的机器上，hbase的临时目录默认是放在/tmp的，而linux的/tmp目录是会被定期清理的(参考linux系统的tmpwatch)
　　所以解决办法是，修改hbase-site.xml，指定hbase.tmp.dir，这样hbase的tmp目录不会被定时清理，over~
