Description

The issue is that OOTB clients often face timeouts when using HMS since many operations in the HMS completes are long running (e.g. many operations on a table with many partitions). A few supporting pieces of information:

• The default value of hive.metastore.client.socket.timeout is 20 seconds.
• Since the timeout is client only, the server happy continues doing the requested work
• Clients retry after a small delay to perform the requested work again, often while the server is still trying to complete the original request
• A few tests have actually increased this value in order to pass reliably.
