------------------------------------

Adding link to the code that is tied to a specific commit hash so the line doesn't change
as code does: [https://github.com/apache/hive/blob/ec6af1bc775b8bb8807e6bcdb86afb05b11ac833/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L1967-L1987]

> When creating a table in HMS, a (HD)FS directory will be [created|https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L1983]
even for the table even for table stored and managed by other systems specified by Hive Storage
Handler. It is ideal to skip directory creation in such case (same for dropping a table).
