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

["Brock Noland (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-7140?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14011640#comment-14011640 ] 

Brock Noland commented on HIVE-7140:
------------------------------------

I propose we increase the default timeout to 5 minutes, because in the current state false positives are extremely common. Increasing this to 5 minutes means that true positives, timing out when the HMS is actually down, will take considerably longer. I believe this to be reasonable trade-off since true positives are rare.

> 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
