in memory error
URL: https://github.com/apache/hive/pull/585
 
 
   Fix: [#HIVE-21555](https://issues.apache.org/jira/browse/HIVE-21555).
   
   The cached thread pool is proper when the task is light-weight and the number of sub-threads
are not too many. Otherwise, fixed thread pool should be used to avoid OutOfMemoryError.

> In the program, since the number of instances (instances = llapRegistryService.getInstances().getAll();)
is not known ahead of time, it has a high risk in causing OutOfMemoryError when too many threads
are created. Therefore, to ensure security, a fixed number of thread pool should be used,
which can be freely configured and also enables running multiple instances concurrently but
is free from the above error.
