> Key: PIG-2576
> URL: https://issues.apache.org/jira/browse/PIG-2576
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.9.3
> Reporter: Vivek Padmanabhan
> Assignee: Thomas Weise
> Fix For: 0.10, 0.9.3, 0.11
>
> Attachments: PIG-2576_0.9.patch, PIG-2576_Script_UDF.txt,
> PIG-2576_e2e.patch

>
> We read a file in the UDF constructor. (The file is transferred to the
> compute nodes via distache)
> To avoid this case in the front-end while the script is in the compile stage,
> we differentiate between front end and back end execution depending upon a
> condition ( UDFContext.getUDFContext().getJobConf() == null )
> This was working till Pig 0.9.1, in the current Pig 0.9 version this is
> breaking.
> ie, If I have any 'fs' commands after the STORE statement, the GruntParser
> invokes the udf constructor again and the above condition check returns false
> causing errors.
