Re: Copy data from Mainframe to HDFS
in mainframe you can have 3 type of datasources
--flat files
--VSAM files

DB2 or IMS supprt the export utilities to copy the data into flat file
which you can get through ftp/sftp
VSAM file can be exported using IDCAMS utility
flat files can be get using the ftp/sftp
