HDP3.0.1+Ambari2.7addnewhost报错之不创建service用户

通过Ambari增加新的host时候，总是不能自动增加service账号，如hdfs, hive等。

解决办法：修改HDP参数 ignore_groupsusers_create

# python configs.py --help

1.查看参数文件中ignore_groupsusers_create的值：

# cd var/lib/ambari-server/resources/scripts

# python configs.py -u admin -p admin -n $cluster_name -l $ambari_server -t 8080 -a get -c cluster-env |grep -i ignore_groupsusers_create

"ignore_groupsusers_create": "false",

2.修改ignore_groupsusers_create的值：

# python configs.py -u admin -p admin -n $cluster_name -l $ambari_server -t 8080 -a set -c cluster-env -k ignore_groupsusers_create -v ture

把ignore_groupsusers_create从false改成ture，重新add host,问题解决

3.查看配置文件路径

[root@xxxxxxxxx ~]# find -name *cluster-env*
