Ah @vanzin, I didn't understand your suggestion. `CommandBuilderUtils`
needs modified to escape comma.
But I think we still need to modify `spark-class2.cmd` as well.
When we execute `bin\spark-shell.cmd --jars "C:\Path to\jar1.jar,C:\Path
to\jar2.jar"`,
we get following with original `spark-class2.cmd` even if
`CommandBuilderUtils` is fixed to escape comma.
`... --jars "C:\Path to\jar1.jar C:\Path to\jar2.jar" ...`
but we get with my PR `spark-class2.cmd`
`... --jars "C:\Path to\jar1.jar,C:\Path to\jar2.jar" ...`
Two job at the same time is surely a problem, so added random string to the
filename to reduce the probability this problem occurs.
I know it's better to solve this problem without using temporary file if
possible, but I have no idea now. If you've got any suggestion, please let me
know.
I'd really like to replace all *.cmd to powershell rather than write ugly
codes like this....
