[jira] [Commented] (OOZIE-2150) Shell launcher should print shell script

["Jacob Tolar (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OOZIE-2150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14389179#comment-14389179 ] 

Jacob Tolar commented on OOZIE-2150:
------------------------------------

I agree that this would be a nice feature, but it won't work nicely all the time - a shell action isn't necessarily running a script (you can ship and run a binary, or use an interpreter in <exec> and a a script as an argument). 

I imagine you could catch many/most cases if you use a library (e.g. http://tika.apache.org/ ) to guess the type of file in <exec>, and print it if it doesn't look like an executable.

if this approach makes sense, I could work on this.
