Can you read the data off backup tapes and dump it to flat files?

So, you need to move all your data to a HDFS cluster to use data in MapReduce jobs if you want to make the calculations with Hadoop.

We need to sort them and then use them with different jobs on mainframe for report generation. I was wondering was there any way I could integrate the mainframe with hadoop do the sorting and keep the file on the sever itself ( I do not want to ftp the file to a hadoop cluster and then ftp back the sorted file to Mainframe as it would waste MIPS and nullify the advantage ). This way I could save on MIPS and ultimately improve profitability. Thank you in advance *------------------------* Cheers !!! Siddharth Tiwari Have a refreshing day !!!
