What Should I Do If an Alarm Indicating Insufficient Memory Is Reported During Spark Task Execution?
Symptom
When a Spark task is executed, an alarm indicating insufficient memory is reported. The alarm ID is 18022. As a result, no available memory can be used.
Procedure
Set the executor parameters in the SQL script to limit the number of cores and memory of an executor.
For example, the configuration is as follows:
set hive.execution.engine=spark; set spark.executor.cores=2; set spark.executor.memory=4G; set spark.executor.instances=10;
Change the values of the parameters as required.
