Subject [jira] Updated: (PIG-327) testShellFuncSingle/Multiple fail in TestBuiltin
Date Fri, 29 Aug 2008 12:37:44 GMT

     [ https://issues.apache.org/jira/browse/PIG-327?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Shravan Matthur Narayanamurthy updated PIG-327:
-----------------------------------------------

    Status: Patch Available  (was: Open)

Had to fix src/org/apache/pig/impl/builtin/ShellBagEvalFunc.java. I thought the earlier code
looked fine as it uses the os.flush() method to signal the shell cmd to compute the output.
However, this did not seem to work. So added a call to the finish() method where we explictly
close the stream. Also for it to work for other inputs, we also need to set the reference
to os to null. This fixes it.

So this reduces the 2 errors & 1 failure in TestBuiltin to 1 error in testSumFinal

Please take a look at the patch. The only thing is we create the process for every input tuple.
I feel that the earlier code should have worked but somehow the flush is not doing its function.
Only an explicit close starts the process going.
