Key: HADOOP-7174
URL: https://issues.apache.org/jira/browse/HADOOP-7174
Project: Hadoop Common
Issue Type: Bug
Reporter: Uma Maheswara Rao G
Priority: Minor
When we perform copyToLocal operations from commandLine and if src Path is
invalid
srcFS.globStatus(srcpath) will return null. So, when we find the length of
resulted value, it will *throw NullPointerException*.
Since we are handling generic exception , it will display null as the message.
