将Hive Thrift server 添加到服务后台运行

1. 将hive 的metastore用mysql连接储存

2 在/etc/init.d/文件夹中编辑文件hive-thrift

#!/bin/bash
# init script for Hive Thrift Interface.
#
# chkconfig: 2345 90 10

exit $RETVAL

新建文件并对文件添加权限

touch /var/run/hive-thrift.pid

touch /var/log/hive-thrift.log

touch /var/run/hive-thrift-java.pid

chown hadoop:hadoop /var/run/hive-thrift.pid

chown hadoop:hadoop /var/log/hive-thrift.log

chown hadoop:hadoop /var/run/hive-thrift-java.pid

将hive-thrift添加到服务中并设置为开机启动

chmod +x /etc/init.d/hive-thrift

chkconfig --add hive-thrift

chkconfig hive-thrift on
