We are getting continuous PartialGroupNameException for a specific user account.
Below is the sample error snippet.
If I am using -- option from the command line, I am getting the group details. I am not sure why this error is being logged. Any thoughts?
# groups -- -SERV-CHEF
groups: -SERV-CHEF: no such user
# groups -- -SERV-CHEF@domain
Basically issue is the Hadoop is running an id command against the user and not including
-- in front of the user if the username starts with a -.
3. Seems like this userid needs its Unix groups to perform some action on HDFS which is throwing this error (eg writing to a directory using group permissions). This is because the group lookup is not working due to above mentioned issue.
