RE: Copy data from Mainframe to HDFS
Hi Balamurali,

As per my knowledge, there is nothing in the hadoop which does exactly as per your requirement.

You can write mapreduce jobs according to your functionality and submit hourly/daily/weekly or monthly . And then you can aggregate the results.

If you want some help regarding Hive, you can ask the same in Hive mailing list.

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<http://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.

Hello Sandeep,

You don't have to convert the data in order to copy it into the HDFS. But you might have to think about the MR processing of these files because of the format of these files.

You could probably make use of Sqoop<http://sqoop.apache.org/>.

I also came across DMX-H a few days ago while browsing. I don't know anything about the licensing and how good it is. Just thought of sharing it with you. You can visit their page<http://www.syncsort.com/en/Data-Integration/Home> to see more. They also provide a VM(includes CDH) to get started quickly.

Warm Regards,

Hi ,

"How to copy datasets from Mainframe to HDFS directly?  I know that we can NDM files to Linux box and then we can use simple put command to copy data to HDFS.  But, how to copy data directly from mainframe to HDFS?  I have PS, PDS and VSAM datasets to copy to HDFS for analysis using MapReduce.

Also, Do we need to convert data from EBCDIC to ASCII before copy? "
