Description

Since we have multiple Jira's in trunk for common and hdfs, I am creating another jira for this issue.

This patch addresses the following:

1. Provides FileUtil API for list and listFiles which throws IOException for null cases.
2. Replaces most of the code where JDK file API with FileUtil API.
