错误一览

开启hbase后hadoop崩溃。重启hadoop。

• start-all.sh启动hadoop顺利（单节点）

[hadoop@master logs]$ start-all.sh

• 能顺利进入hadoop网页

http://ip:9870

• 检查各个日志文件

more hadoop-hadoop-datanode-master.log|grep ERROR
more hadoop-hadoop-namenode-master.log|grep ERROR
more hadoop-hadoop-nodemanager-master.log|grep ERROR
more hadoop-hadoop-resourcemanager-master.log|grep ERROR
more hadoop-hadoop-secondarynamenode-master.log|grep ERROR

• 发现错误

2020-05-24 16:10:01,887 ERROR org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode: Exception in doCheckpoint

• 启动hbase

start-hbase.sh

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/hadoop/hbase-2.0.5/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]

• jps

• 此时hbase和hadoop的网址均进不去，查看hbase日志

more hbase-hadoop-master-master.log|grep ERROR
more hbase-hadoop-regionserver-master.log|grep ERROR

• 其中hbase-hadoop-master-master.log近期有如下报错

2020-05-24 16:19:01,071 ERROR [Thread-14] master.HMaster: Failed to become active master
2020-05-24 16:19:01,084 ERROR [Thread-14] master.HMaster: ***** ABORTING master master,16000,1590308251582: Unhandled exception. Starting shutdown. *****

就是这个原因导致shutdown。

解决方案

• 查询网上方案，但我已在配置文件 hbase-site.xml中添加如下：

<property>
<name>hbase.unsafe.stream.capability.enforce</name>
<value>false</value>
</property>

• 最后通过删除hbase库（我目前里面没有内容）

hadoop fs -rm -r /hbase

重启hbase,jps
