本文详细记录了HBase集群从节点启动时遇到的HRegionServerAborted错误，并提供了两种解决策略：一是修改HBase配置文件中的hostname为IP地址；二是确保ZooKeeper正常运行并同步服务器时间，以解决集群服务器时间不统一导致的服务异常关闭问题。

hbase集群从节点报错如上

启动集群后，主节点进程存在：

[root@master ~]# jps
3968 NameNode
1127 HistoryServer
2153 DataNode
29161 RunJar
4906 JobHistoryServer
25515 NodeManager

5786 ThriftServer

从节点；

[root@slave2 ~]# jps
15892 QuorumPeerMain
27256 Worker
11052 Jps
21773 NodeManager
3006 DataNode
未发现：

HRegionServer服务；web界面也未发现从节点的habse进程服务

但是从节点hbase服务可以用

[root@slave2 ~]# hbase shell

解决办法：1：hbase的配置文件中将hostname改为ip；

如果第一种办法无法解决上述报错。再查看zookeeper是否正常启动。

2；在zookeeper正常的情况下还是无法解决这个问题那就是服务器时间未同步的原因，集群的服务器时间不统一，不同步，导致hbase从节点服务启动起来后异常关闭。需要同步服务器时间。然后就可以解决这个报错。
