cli timeouts

Hey Hive gurus -

Does anyone know how the CLI handles metastore connection timeouts? It
seems if I leave a CLI session idle more than
hive.metastore.client.socket.timeout seconds then run "show tables",
the cli hangs for the timeout then throws a SocketTimeoutException.
Restarting the CLI and running the same "show tables" always works.

Does anyone else see this? My hive.metastore.client.socket.timeout is
set to 60 - is that a reasonable value?

Interesting - this issue would certainly go away with local mode as
there's no thrift call to fail. I'd very much prefer to run HMS as a
centralized service though.

Thanks for the info - I'll have to take a look at how the thrift
client handles timeouts/reconnects/etc.

Re: cli timeouts

The two setup options are:

cli->thriftmetastore->jdbc

cli->jdbc (used to be called local mode)

localmode has less moving parts so I prefer it.

Oh interesting - you're saying instead of running a single
HiveMetaStore thrift service, most users use the embedded
HiveMetaStore mode and have each CLI instance connect to the DB
directly?

I feel that that interface is very rarely used in the wild. The only
use case I can figure out for it is people with very in depth hive
experience that do not wish to interact with hive through the QL
language. That being said I would think the coverage might be a little
weak there. With the local metastore users have data nucleus providing
support for reconnection etc.

Re: cli timeouts

Posted by Travis Crawford <tr...@gmail.com>.
I'm using the thrift metastore via TFramedTransport. What value do you
specify for hive.metastore.client.socket.timeout? I'm using 60.

If I open the CLI, run "show tables", wait the timeout period, then
run "show tables" the CLI hangs in:

"main" prio=10 tid=0x000000004151a000 nid=0x448 runnable [0x0000000041b42000]
