Description

We have seen this issue during a Hive test. Where Hive tries to create a temp file using File.createTempFile(..) and it throws:

Exception in thread "main" java.io.IOException: No such file or directory
	at java.io.UnixFileSystem.createFileExclusively(Native Method)
	at java.io.File.checkAndCreate(File.java:1704)
	at java.io.File.createTempFile(File.java:1792)
	at java.io.File.createTempFile(File.java:1828)
	at Test.main(Test.java:13)

Because it literally sees "$PWD/tmp" as the temp directory path.

$PWD need to be evaluated before being used in setting the property "java.io.tmpdir" in MapReduceChildJVM.java.
