Subject [jira] [Commented] (HIVE-7140) Bump default hive.metastore.client.socket.timeout to 5 minutes

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

Hi,

Good point, this is obviously just to improve OOTB behavior today. I have opened HIVE-7195
to track improvements to the MS itself.

> 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.
