Description

HIVE-17563 changed metrics code to use local file system operations instead of Hadoop local file system operations. There is an unintended side effect - hadoop file systems create the directory if it doesn't exist and java nio interfaces don't. The purpose of this fix is to revert the behavior to the original one to avoid surprises.
