Ahmed Hussein commented on HDFS-15119: -------------------------------------- Checking the failed unit test cases. It looks like {{TestDatanodeRegistration}} was failing for some time. It is not related to that patch. > Allow expiration of cached locations in DFSInputStream > ------------------------------------------------------ > > Key: HDFS-15119 > URL: https://issues.apache.org/jira/browse/HDFS-15119 > Project: Hadoop HDFS > Issue Type: Improvement > Components: dfsclient > Reporter: Ahmed Hussein > Assignee: Ahmed Hussein > Priority: Minor > Attachments: HDFS-15119.001.patch, HDFS-15119.002.patch > > > Staleness and other transient conditions can affect reads for a long time > since the block locations may not be re-fetched.
