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

Sat Oct 5 07:47:55 CST 2019 Starting master on gfs01 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
