RANGER-5424:Hive Insert command failed in Ranger Docker setup due to authentication and authorization issue.

[rameeshm]

Hive Insert command failed in Ranger Docker setup due to authentication and authorization issue.

1. apache-tez-0.10.4-bin.tar.gz failed to copy into /apps/tez due to lack of kerberos token present while copying.
2. user "hive" needs hdfs RWX permission to create folder and copy tez jar for insert to succeed.

What changes were proposed in this pull request?

1. have default policy for user "hive" in hdfs repo.
2. To the kinit for the hive and create necessary hdfs folder / files in /opt/tez folder for the Tez to work correctly during INSERT operation.

How was this patch tested?

Testing in the DOCKER.

Pull request overview

This PR addresses authentication and authorization failures in the Ranger Docker setup when executing Hive INSERT commands. The core issue was that the hive user lacked both Kerberos tokens for authentication and HDFS permissions for writing Tez libraries and temporary files required for INSERT operations.

Key Changes:

• Added Kerberos authentication (kinit/kdestroy) for hive user when performing HDFS operations in Kerberos-enabled environments
• Created default HDFS policy granting hive user read/write/execute permissions for Tez operations
• Refactored HDFS operations to use the hive user instead of hdfs user when Kerberos is enabled
