Spark, Hive, and Yarn Are Unavailable Due to Insufficient Disk Capacity

Issue

A critical alarm indicating that Spark, Hive, and Yarn are unavailable is generated due to insufficient disk capacity.

Symptom

The disk capacity of the cluster created by the user is insufficient. As a result, a critical alarm indicating that Spark, Hive, and Yarn are unavailable is generated.

Cause Analysis

Insufficient cluster disk capacity affects HDFS data writing. When the HDFS disk space usage exceeds the threshold, HDFS becomes abnormal. As a result, Spark, Hive, and Yarn are unavailable.

The alarm indicating that Spark, Hive, and Yarn are unavailable is generated due to insufficient disk capacity of the cluster. After the disk capacity is expanded, the alarm is cleared. Therefore, it can be determined that the HDFS function fault is caused by insufficient disk capacity.

Procedure

For details about how to clear the alarm triggered by insufficient disk capacity, see ALM-12017 Insufficient Disk Capacity.
