------------------------


When submitting a job with an environment variable containing the "," character,
only the portion of the variable value preceeding the comma is used in the
environment exported to the client.

==== To replicate:

- Create a job script (in this example, "grid_echo_FOO") with the
  following content:

#!/usr/bin/env bash
echo "FOO='${FOO}'"

- Submit the script for execution:

$ DIR_LOG=`pwd`/stdout
$ qsub -o ${DIR_LOG}/stdout -v 'FOO=bar,baz' grid_echo_FOO
Your job ... has been submitted
$ # Wait for the job to execute
$ cat ${DIR_LOG}/stdout
FOO='bar'
$

==== Workaround:

If the alternate form of the environment variable export is used
where only the variable name is provided, the environment variable
is exported properly.  Example:

$ FOO='bar,baz' qsub -o ${DIR_LOG}/stdout -v 'FOO' grid_echo_FOO
Your job ... has been submitted
$ # Wait for the job to execute
$ cat ${DIR_LOG}/stdout
FOO='bar,baz'
$
