Subject [jira] [Commented] (HIVE-8629) Streaming / ACID : hive cli session creation takes too long and times out if execution engine is tez
Date Tue, 28 Oct 2014 19:27:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-8629?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14187329#comment-14187329
] 

Roshan Naik commented on HIVE-8629:
-----------------------------------

[~alangates]  the without setugi, the directories created by the metastore during add partition
etc are done as hive user instead of the client user of the metastore process, consequently
leading to incorrect permissions and later failure to stream to those directories.

WRT Log.info(): Since this done each time a new connection is created, which occurs multiple
times over the duration of a long running streaming process, to reduce noise in the log output
.. i am wondering if we should document this instead of log.info()  ? Either I am fine. Let
me know what you think.

> When creating a hive session to run basic "alter table create partition"  queries, the
session creation takes too long (more than 5 sec)  if the hive execution engine is set to
tez.
> Since the streaming clients dont care about Tez , it can explicitly override the setting
to mr.
