Re: Copy data from Mainframe to HDFS

Hi,

I configured hadoop-1.0.3, hbase-0.92.1 and hive-0.10.0 .
Created table in HBase.Inserted records.Processing the data using Hive.
I have to show a graph with some points ( 7 - 7 days or 12 for one year).In
one day records may include 1000 - lacks.I need to show average of these
1000 - lacks records.is there any built in haddop mechanism to process
these records fast.

Also I need to run a hive query  or job (when we run a hive query actually
a job is submitting) in every 1 hour.Is there a scheduling mechanism in
hadoop to handle thsese
Please reply.
