To close the loop, I think the problem comes from running 32 bit ubuntu VM
on vmware inside windows 7 host.
After replacing the 32 bit vm with a 64 bit one, problem is gone...

As you expected, there is no documentation on it (like other optimizers)
Javadoc of the class might be helpful but seemed not in detail enough.

Local mode is fast. In particular older version pf hadoop take a lot of
time scheduling tasks and a delay betwen map and reduce phase.
Local mode really helps with those little delays.

Hi Experts,
I'm working with Teradata query conversion to hive environment (Hive
version 0.10.0).The challenge that am facing here is in converting the
below line in query.
In SELECT clause:

ORDER BY COUNTER) AS CLMST_ORDR_NBR

Hi,
I compared the HiveServer 1 and HiverServer 2 Thrift implementation.
I'm asking myself why the straight forward methodes like .execute(String

Hi Owen,
I’m curious about this advice about partitioning. Is there some fundamental
reason why Hive
is slow when the number of partitions is 10,000 rather than 1,000? And the

that you mention are they going to be in version 12? Is there a JIRA raised so
that I can track them?

Thanks Navis,
This is a very interesting class which I feel pretty sure that I would never
have found.
Are there any descriptions, motivations, documentation or examples anywhere?
I suspect that there's nothing other than the source itself, but I had to ask.

So I found the getRequiredFiles() and getRequiredJars() methods that were added
in HIVE-2561, and implemented getRequiredJars() to provide the full local paths
