regionserver.HRegionServer: Failed construction RegionServer

1、启动hbase以后，jps发现很快HMASTER进程就退出了。

[root@gfs01 data]# jps 6482 Jps 4083 QuorumPeerMain 2180 SecondaryNameNode 12582 -- process information unavailable 2364 ResourceManager 1967 NameNode

没有HMaster进程。

2、查看hbase启动日志

[root@gfs01 logs]# pwd /usr/hbase-2.1.6/logs [root@gfs01 logs]# ll total 7212 -rw-r--r-- 1 root root 1634526 Oct 8 00:47 hbase-root-master-gfs01.log -rw-r--r-- 1 root root 492 Oct 8 00:37

3、解决

将/usr/hbase-2.1.6/lib/client-facing-thirdparty/htrace-core-3.1.0-incubating.jar文件拷贝到/usr/hbase-2.1.6/lib/下面即可

cp /usr/hbase-2.1.6/lib/client-facing-thirdparty/htrace-core-3.1.0-incubating.jar /usr/hbase-2.1.6/lib/

4、重新启动hbase

start-hbase.sh
