EXAMPLES

IMPORTING BY SPLITTING TO SPECIFIED NUMBER OF FRAGMENTS

The following is an example using gfimport_text to import a source_file as gfarm:file by splitting to 8 fragments.

 gfsched -N 8 | gfimport_text -H - -o gfarm:file source_file
 

IMPORTING BY SPLITTING TO SPECIFIED NUMBER OF FRAGMENTS FOR PARTICULAR PROGRAM

The following is an example using gfimport_text to import a source_file as gfarm:file by splitting to 8 fragments to be processed by gfarm:prog program.

 gfsched -N 8 -p gfarm:prog | gfimport_text -H - -o gfarm:file source_file
 

IMPORTING INTO SAME DISPOSITION WITH AN EXISTING GFARM FILE

The following is an example using gfimport_text to import a source_file as gfarm:file into same disposition with existing file gfarm:template.

 gfsched gfarm:template | gfimport_text -H - -o gfarm:file source_file
