Hive Metastore 启动成功又失败

hive 在正常使用中 metastore 忽然停掉，查看日志，报一下错误：

2017-06-19 12:11:15,134 ERROR [main]: metastore.HiveMetaStore (HiveMetaStore.java:startMetaStore(6080)) - org.apache.thrift.transport.TTransportException: Could not create ServerSocket on address 0.0.0.0/0.0.0.0:9083.

这个端口被占的错误，已经存在一个metastore服务，需要停掉再重启。

查看metastore 服务端口：

ps -ef |grep HiveMetaStore

根据找到的pid 杀死该进程：
kill -9 “pid”

最后重启metastore 就可以了
