In that case HBase might help. HBase needs to have unique keys. They are just
bytes, so I guess you can just concatenate multiple columns in your primary key
( if you have a primary key spanning >1 column) to have a key for HBase, so
that duplicates don

Could anyone tell how we could set the commandline arguments ( like -Xmx and
-Xms) for the client (not for the map/reduce tasks) from the command that is

Hi,
I have tried that as well, using -files But it still gives the exact

Thanks,

Hi,
Could anyone please guide me as to how to use the -libjars option in HDFS?

classpath of the node where I am starting the job.

bin/hadoop jar -libjars

proceed beyond the "map 0% reduce 0%" stage. Soon after I get this error:
java.io.IOException: Task process exit with nonzero stat
Hi Deepak,
Maybe I did not make my mail clear. I had tried the instructions in the blog
you mentioned. They are working for me.

Hi,
I am a newbie. I am curious to know how you discovered that all the blocks are
written to datanode's hdfs? I thought the replication by namenode was
transparent. Am I missing something?
Thanks,
