i-总结：
在完全分布式模式下测试hadoop（2.6.0）/hbase（1.0.1.1）时遇到了一个问题。问题是每次创建表时，查询都会冻结，并出现错误“handler.createtablehandler:failed”。空”。尽管如此，当我检查时，表已成功创建。
ii-设置和配置：
我有一个5台机器的简单设置；一个namenode/hmaster、一个resourcemanager/zkquorum和三个从属服务器，其中两个是区域服务器，而第三个是备份hmaster。
iii-问题
hadoop已经启动并运行，但是hbase在我创建一个表之后意外地冻结了。无论是通过hbase shell还是javaapi，行为都是相同的。尽管有冻结的部分，表是每次创建。
正如您在下面的最后一个日志条目中所注意到的，createtablehandler失败，消息为null。
我四处寻找与我相似的帖子，只找到2个。第一个没有答案，第二个建议是重新启动服务器。的确，我尝试过这个解决方案，但不幸的是，它对我不起作用。我尝试过的其他解决方案有：
清洁zk
hbase离线元修复
将hmaster分配给不同的机器。
有人知道这是怎么回事吗？
提前多谢了！
