Impact on the System

If the permission on the Hive default data warehouse is modified, the permission for users or user groups to create databases or tables in the default data warehouse is changed.

Possible Causes

Hive periodically checks the status of the default data warehouse and finds that default data warehouse permission is changed.

Procedure

Check the Hive default data warehouse permission.

  1. Log in to the node where the client is located as user root.
  1. Run the following command to go to the HDFS client installation directory:

    cd Client installation directory

    source bigdata_env

    kinit User who has the supergroup permission (Skip this step for a common cluster.)

  2. Run the following command to restore the default data warehouse permission:

    • Security mode: hdfs dfs -chmod 770 hdfs://hacluster/user/hive/warehouse
    • Non-security mode: hdfs dfs -chmod 777 hdfs://hacluster/user/hive/warehouse

  3. Check whether the alarm is cleared.

    • If it is, no further action is required.
    • If it is not, go to 5.

Collect fault information.

  1. Collect related information in the hdfs://hacluster/user/hive/warehouse directory on the client background.
  2. Contact the O&M personnel and send the collected logs.

Alarm Clearing

After the fault is rectified, the system automatically clears this alarm.
