--------------------------------
Summary: Use checksum in localisation requests
Key: YARN-5289
URL: https://issues.apache.org/jira/browse/YARN-5289
Project: Hadoop YARN
Issue Type: Bug
Reporter: Yesha Vora
Currently, timestamps is being used in localization requests. Because using
timestamps is always pretty brittle. ( we notice a clock jump in the VM.)
For the filesystem supporting getFileChecksum(Path), the checksum can be used
instead of timestamps in localisation requests
