    Description

      In case of any exception while query parsing in `HiveMaterializedViewsRegistry.createMaterialization`, we bail out and there is no hdfs dir cleanup until JVM exit. This leaves behind the staging directories. For a long-running HS2, these staging directories keeps on increasing and can cause limit reached exception.

      Error: Error while compiling statement: FAILED: RuntimeException Cannot create staging directory 'hdfs://aidaprd01/warehouse/tablespace/managed/hive/test.db/testTable/.hive-staging_hive_2023-08-05_06-17-06_711_5516272990801215078-168329': The directory item limit of /warehouse/tablespace/managed/hive/test.db/testTable is exceeded: limit=1048576 items=1048576 

      We should do hdfs directory cleanup for `HiveMaterializedViewsRegistry` thread here
