John,
Please correct me if I didn't understand the problem correctly.
I think in this scenario, it's best to think about the query in terms of
MapReduce. In this case, you would want for each record sent as input to
your mapper, two records to be emitted, one with col2's value and one with
col3's
Hi Parag,
I think your question boils down to:
How does one access Hive metadata from MapReduce jobs?
In the past, when I've had to write MR jobs and needed Hive metadata, I
ended up writing a wrapper Hive query that used a custom mapper and reducer
by using hive's transform functionality to do t
I am trying to do a union, group by, and multi insert all at once. I know
this convoluted but I what I am trying to do is avoid having to scan
through the original table more than once... if I can get all my data from

can use dfsclient read the data easily. So what I thought is one user's data
in hdfs, should only be 700.
Coming to what you said ACLs in HDFS, what my understanding is , t

hadoop jar command. I would like to access hive metadata (read partitions
informations) in this program. I can ask user to set HIVE_CONF_DIR
environment variable before calling my program or ask for any re
hmm .. there's a possibility that the execute and close for a given
statement are not handled by same thrift thread. Can you please verify the
testcase with a single worker thread on the server side ?
You can run the server using following :
hive --service hiveserver --maxWorkerThreads 1 --minWo
