Description

The user sets the value of spark.sql.thriftserver.scheduler.pool.
Spark thrift server saves this value in the LocalProperty of threadlocal type, but does not clean up after running, causing other sessions to run in the previously set pool name.

 

For example

The second session does not manually set the pool name. The default pool name should be used, but the pool name of the previous user's settings is used. This is incorrect.
