关于hbase，zookeeper.MetaTableLocator：验证hbase：meta，.NotServingRegionException

Question

我使用hadoop2.7.3，Hbase 1.2.3，zookeeper 3.4.9。

每次我停止Hbase并重新启动它时，都会抛出异常：

  [hadoop01:16000.activeMasterManager] zookeeper.MetaTableLocator: Failed        verification of hbase:meta,,1 at address=hadoop05,16020,1478663588885, exception=org.apache.hadoop.hbase.NotServingRegionException: Region hbase:meta,,1 is not online on hadoop05,16020,1478664215143

我已经搜索了异常，但原因（即hdfs saftemode或服务器的日期）都不满足我的情况。以及zookeeper的日志：

hbase-sie.xml

zoo.cfg

Answer 1

我也遇到了这个问题。 首先，您可以尝试修复数据

  

bin / hbase清理

     

用法：hbase clean（--cleanZk | --cleanHdfs | --cleanAll）   选项：

--cleanZk   cleans hbase related data from zookeeper.
--cleanHdfs cleans hbase related data from hdfs.
--cleanAll  cleans hbase related data from both zookeeper and hdfs.

此外，您可以删除整个动物园管理员的数据， 可以由hbase-site.xml或zoo.cfg甚至是默认目录配置，您可以检查配置文件
