Alarm Attributes

Alarm Parameters

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.

Handling Procedure

Check the Hive default data warehouse permission.

1. Log in to the node where the client is located as user root.

2. 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.)

3. Run the following command to restore the default data warehouse permission:
   • Kerberos authentication is enabled for the cluster (the cluster is in security mode):

     hdfs dfs -chmod 770 hdfs://hacluster/user/hive/warehouse

     hdfs dfs -chown hive:hive hdfs://hacluster/user/hive/warehouse

   • Kerberos authentication is disabled for the cluster (the cluster is in normal mode):

     hdfs dfs -chmod 777 hdfs://hacluster/user/hive/warehouse

     hdfs dfs -chown hive:hive hdfs://hacluster/user/hive/warehouse

4. Check whether the alarm is cleared.
   • If it is, no further action is required.
   • If it is not, go to 5.

Collect fault information.

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

Alarm Clearance

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