PleaseHoldException

启动hbase后,输入list报错:

ERROR: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing

检查文件:

hdfs fsck / -locations -blocks -files

当时没有截图,其中有段如下:

Total symlinks:        0 (Files currently being written: 8)

发现有8个文件处于打开状态。说明当时正在写文件时断电了,因此需要删除这8个文件。

 

查看哪些文件正在打开中:

 hadoop fsck / -openforwrite

依次删除文件:

Hadoop dfs -rm

/hbase/WALs/z1,60040,1513823979473/z1%2C60040%2C1513823979473.default.1513823986000

再次检查:

 hadoop fsck / -openforwrite

再重启hbase即可。
