EXAMPLES

Example 1. 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

Example 2. 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

Example 3. 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
