But I don't want to create user and group in the linux of each hive
client. Can you tell me how to use “hadoop groups $user”
Users and groups are interpreted by HDFS, Hive and all Hadoop components.
So you need to have user to group mappings either in linux or in LDAP/AD.
If I am not wrong,
Hi，Bosco
Last time you said that :
The groups should work. The best what to test it to do “hadoop groups $user”
and see what is returning. And use the same groups in the policy.
1. I found that ,only when I use the command groupadd,useradd to create
user and group in the linux of hive
