[jira] [Commented] (AMBARI-9882) Pig Service check fails in a
Kerberized cluster
[ https://issues.apache.org/jira/browse/AMBARI-9882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14344069#comment-14344069 ]
Alejandro Fernandez commented on AMBARI-9882:
---------------------------------------------
This occurs due to several things
1. params.py in Pig creates a partial object for HdfsDirectory where
{code}
hdfs_user=hdfs_principal_name if security_enabled else hdfs_user
{code}
2. The value above is then used by dynamic_variable_interpretation.py, which calls HdfsDirectory, and ends up kinit as the user whose value comes from hdfs_user. The problem is that "hdfs@EXAMPLE.COM" in a kerberized cluster is not a valid user to perform the kinit command as.
Further, in the function _copy_files, the call to CopyFromLocal also needs to execute the commands as ambari-qa, instead of hdfs@EXAMPLE.COM, even while granting file ownership permission to the latter user.
