Subject [jira] [Commented] (HIVE-9584) Hive CLI hangs while waiting for a container
Date Thu, 12 Mar 2015 16:20:40 GMT


Hari Sekhon commented on HIVE-9584:

I've noticed this problem today too.

I suggest container start be done in another thread in the background and the CLI be presented
to the user for metadata operations without requiring a tez container.

> The Hive CLI, with Tez set as the execution engine, hangs if a container cannot be immediately
be allocated as the Tez application master.  From a user perspective this behavior is broken.
> Users should be able to start a CLI and execute hive metadata commands without needing
a Tez application master.  Since users are accustomed to queries with Hive on MapReduce taking
a long time, but access to the CLI being near instantaneous, the correct behavior should be
to wait for a query to be run before starting the Tez application master.
> This behavior is avoided with the Beeline CLI since it connects through HiveServer2,
however many users are accustomed to using the Hive CLI and should not be penalized for their
choice until the Hive CLI is completely deprecated.
