How can I escape special characters in the YARN service "launch_command" field such as , and =?
I am using the following YARN service definition and need to pass input values that contain commas and equals signs. I have tried single quotes, escaped double quotes, and double escapes on the characters themselves (e.g. \\,), but nothing seems to work. The launch_command is always split on commas (e.g. "input1,a\\,b" => "input1", "a\", "b") and is always truncated at the first equals sign (e.g. "input1,'abc=def'" => "input1", "'abc").
