Description

Problem triggers in HDFS, but the change is in Hadoop-Common, Since the listFiles is defined in Hadoop-Common.

Scenario:

ListFiles With recursive: 

• Fetches a dir say /dir, which has some /dir/s1...s10
• Recursive is set to true: It goes and tries on say /dir/s5 and /dir/s5 got deleted by that time
• The entire operation fails with FNF

Hive Cleaner uses listFiles with recursive true and this impacts that
