HBase--PleaseHoldException和TableNotDisabledException

2016-06-02

Hadoop HBase

PleaseHoldException
TableNotDisabledException

　　解决问题的能力，就是属于经验的一部分。慢慢积累，今天操作hbase的时候报了两个错误，PleaseHoldException和TableNotDisabledException，具体异常信息如下：

PleaseHoldException

异常信息：
ERROR: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing

具体日志如下

hbase(main):001:0> enable 't_2'
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/local/hbase-0.98.8/lib/slf4j-log4j12-1.6.4.jar!/org/slf4j/impl/StaticLoggerBinder.class]

Here is some help for this command:
Start enable of named table:
  hbase> enable 't1'
  hbase> enable 'ns1:t1'

解决：

对于网上的说法很多，大部分人说是ip，主机名映射的问题，ubuntu 需要将/etc/hosts 中的127.0.1.1 修改为 127.0.0.1。这个问题主要就是hadoop异常，如果是刚启动的集群就需要检查一下配置文件，如果集群之前是正常的这时我们就需要查看一下各个节点是否异常。
我的错误出现在节点异常，修复后重启hadoop就行了，这个问题有些不确定因素展示只能提示到这里，以后要时候新发现会过来再次更新该博客。

TableNotDisabledException

异常信息：
ERROR: org.apache.hadoop.hbase.TableNotDisabledException:

具体日志如下

Here is some help for this command:
Start enable of named table:
  hbase> enable 't1'
  hbase> enable 'ns1:t1'

我在enable或者disable的时候报错，TableNotDisabledException。

解决

我们需要将zookeeper里面的表信息删除，具体操作如下：

运行命令
hbase zkcli
删除表信息，如我这里表为‘t_2’
delete /hbase/table/t_2

操作信息如下
