Question

I-摘要：

我在完全分布式模式下测试Hadoop（2.6.0）/ Hbase（1.0.1.1）时遇到了问题。问题是每次我创建一个表时，查询会冻结，错误＆＃34; handler.CreateTableHandler：失败。空＆＃34 ;.尽管如此，当我检查时，表格已成功创建。

II-设置和配置：

我退出了5台机器的简单设置;一个namenode / HMaster，一个resourceManager / ZKQuorum和三个slave，其中两个是区域服务器，而第三个是备用HMaster。

III- Porblem

Hadoop启动并运行，但在我创建一个表后，HBase出人意料地冻结了。通过HBase shell或Java API执行此操作的行为保持不变。尽管有冷冻的部分，但桌子每次都是创造出来的。

正如您在下面的最后一个日志条目中注意到的那样，createTableHandler失败并且msg为null。

我四处寻找与我类似的帖子，我只发现2. first一个没有答案，在second中，建议重启服务器。实际上，我尝试过这个解决方案，但遗憾的是它并没有为我工作。我试过的其他解决方案是：

清洁ZK
Hbase offlineMetaRepair
将HMaster分配给不同的机器。

有人知道这可能来自哪里吗？

提前非常感谢你！

创建表后，Hbase shell冻结
