我正在尝试在 Cloudera 集群上使用 HBase。HBase 已启动并正常运行，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 集群运行状况的信号。无论如何，如果我在 Cloudera Manager 上检查 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：
