我正在尝试在Cloudera集群上使用HBase。 HBase启动并运行没有错误，但是当我尝试进入HBase shell并创建一个新表时：
create 'test', 'cf1'
我收到以下错误：
Table Namespace Manager not ready yet
Cloudera Manager不会发出有关HBase群集运行状况的问题。无论如何，如果我检查Cloudera Manager上的HBase日志，我会发现很多错误，如下所示：
Can't open after 24 attempts and 310225ms for hdfs://hmaster:8020/hbase/WALs/slave8,60020,1416510428414-splitting/slave8%2C60020%2C1416510428414.1416510442205
或者：

我的群集出了什么问题？
