Hi @han-wang , why do we need a \ before "?
The scripts work for me even without this patch. Do you encounter any problem?

[han-wang]

$MAP_JAVA_OPTS isn't set success

[carsonwang]

Thanks for the explanation, @han-wang . This works!
I noticed anther issue. It seems the MAP_JAVA_OPTS is not probed correctly from mapred-site.xml?

[han-wang]

yes, the default is from mapred-site.xml, but we can't update mapred-site.xml at on line, i need to be in the client incoming parameters.

OK. I'll merge this first. We can fix the other issue later in another PR. Thanks for the fix, @han-wang !
