Greenplum添加segment节点

概述注意：如果master配置了standby master，添加的segment必须要有mirror segment存在，否则报错。 1 查看某张表的数据分布情况 tutorial=# select gp_segment_id, count(*) from otp_r group by gp_segment_id; gp_segment_id | count ---------------+

1查看某张表的数据分布情况

tutorial=# select gp_segment_ID,count(*) from otp_r group by gp_segment_ID; gp_segment_ID |  count  ---------------+---------             0 | 1024552(1 row)

2关闭iptables和selinux 3root用户配置ssh互信

略

4创建gpadmin用户

/usr/sbin/useradd gpadmin -d /home/gpadmin -s /bin/bash

5gpadmin用户配置ssh互信

略

6编辑new_hosts_file文件

该文件中仅包含新增节点主机名

7创建inputfile
