We only use their java driver, but do not change any code, is that also
aware of GPL license?
I'm glad if it could be in hive-contribs, thanks.

Great work YC. Alas, mongodb is GPL licensed, otherwise we could have it in
hive-contribs (ofcourse only if you have decided it to contribute).

Rohan,
I took a look at the source code and wanted to share a couple of things:
1) Make sure the following 2 properties are being set to true (they are false
by default):
hive.optimize.skewjoin
hive.auto.convert.join
2) The Hive source code that is causing the exception is:
String path =
Nice idea! I have worked a bit with Mongo and am leaning towards hive .
This could be a nice combo. will check it out (pun intended)

I just have a quick and dirty implementation of a MongoDB storage handler
for HIVE, the project is hosted on GitHub:

Since Hive table do not support 'update' efficiently, we use MongoDB to
store those data, e.g. 'meta' data like user profile info, which need
Hi Mark,
Apologies for the thin details on the query :)
Here is the error log http://pastebin.com/pqxh4d1u the job tracker
doesn't show any errors.
I am using hive-0.7, I did set a threshold for the query and sadly i

Rohan,
The short answer is: I don't know:-) If you could paste the log, I or someone
else of the mailing list could be able to help.
BTW, What version of Hive were you using? Did you set the threshold before
running the query? Try to find some documentation online if can tell what all

Hi Mark,
I have tried setting hive.optimize.skewjoin=true, but it get a
NullPointerException after the first stage of the query completes.
Why does that happen?

Ayon,
I see. From what you explained, skew join seems like what you want. Have you
tried that already?
Details on how skew join works are in this presentation. Jump to 15 minute mark
if you want to just listen about skew joins.

Hey all,
I'm having some trouble with the HBase bulk load, following the instructions
from https://cwiki.apache.org/confluence/display/Hive/HBaseBulkLoad. In the
last step ("Sort Data") I get:
java.lang.RuntimeException: Hive Runtime Error while closing operators:
java.io.IOException: No files
I'm running into the same issue, and I see that it's addressed in HIVE-2223.
In the meantime, I'm getting an error when trying to use the reflect() function
:
SELECT reflect("org.apache.commons.lang.StringUtils", "join", collectedSet), ...

Hi,
Pls check this property " javax.jdo.option.Multithreaded " it is introduced in
trunk in 0.8 version as part of HIVE-2022 . If the value is true it will make
JDO thread safe. Analyze this property can be added to 0.6 version or not if it
works.
Hope it helps,
