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
