hbase启动异常解决方法_java.io.interruptedioexception at org.apache.hadoo

今天在启动hbase得时候，报如下异常：

ERROR: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing
	at org.apache.hadoop.hbase.master.HMaster.checkInitialized(HMaster.java:2938)
	at org.apache.hadoop.hbase.master.HMaster.listNamespaces(HMaster.java:3264)

重启hbase之后，仍然出现上述异常。推测可能是HDFS中和zk中的hbase没有删除导致。

• 删除zk中的所有/hbase目录

1. 切换到zk中的所有/hbase目录
[root@Hadoop20 azkaban-web]# cd /opt/soft/zk345/bin/
 
2. 执行命令
[root@Hadoop20 bin]# ./zkCli.sh
Connecting to localhost:2181
 
3. 查看所有内容
[zk: localhost:2181(CONNECTED) 0] ls /
[cluster, controller_epoch, brokers, zookeeper, feature, admin, isr_change_notification, consumers, log_dir_event_notification, latest_producer_id_block, config, hbase]
 
4. 删除zk中的所有hbase目录
[zk: localhost:2181(CONNECTED) 4] rmr /hbase
 
5. 查看删除后目录
[zk: localhost:2181(CONNECTED) 5] ls /
[cluster, controller_epoch, brokers, zookeeper, feature, admin, isr_change_notification, consumers, log_dir_event_notification, latest_producer_id_block, config]

• 删除HDFS下所有的hbase目录

[root@Hadoop20 bin]# hadoop fs -rm -r /hbase
Deleted /hbase

下面重启hbase、zookeeper、hadoop就可以了
