Undefined variable is treated as string. ----------------------------------------
Key: HADOOP-6100 URL: https://issues.apache.org/jira/browse/HADOOP-6100 Project: Hadoop Common Issue Type: Bug Components: mapred Affects Versions: 0.20.0 Reporter: Suman Sehgal Priority: Minor This issue is related to HADOOP-2838. For X=$X:Y : Append Y to X (which should be taken from the tasktracker) , if we append to an undefined variable then value for undefined variable should be displayed as blank e.g. NEW_PATH=$NEW_PATH2:/tmp should be displayed as ":/tmp" in child's environment while that variable is being displayed as a string ("$NEW_PATH2:/tmp") in the environemnt. This is happening in case of default task-controller only. This scenario works fine with linux task-controller. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
