[jira] Commented: (PIG-69) NullPointerException in setJobtrackerLocation() in PigContext.java:68

["Alan Gates (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-69?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12562584#action_12562584 ] 

Alan Gates commented on PIG-69:
-------------------------------

One question.  Why did you remove the line:

conf = new JobConf()

at PigContext line 179?  As conf is used in the code subsequent to this it isn't clear to me that it's ok.  Did you test your change in local mode (which is the only codepath that would exercise this change)?
