---------------------------------
Summary: globStatus in feed retention fails in some cases
Key: FALCON-81
URL: https://issues.apache.org/jira/browse/FALCON-81
Project: Falcon
Issue Type: Bug
Reporter: Shwetha G S
If the data path is /data/${YEAR}/${MONTH}/${DAY}/${HOUR}/SomeData, feed
eviction checks for pattern /data/*/*/*/*/SomeData which should be directory.
Glob status on this fails if there is a file /data/2013/01/01/01/file:
Failing Oozie Launcher, Main class [org.apache.ivory.retention.FeedEvictor],

This is because of an issue in glob status. Feed evictor should search with
pattern /data/*/*/*/*/*/{SomeData}
