Steve Loughran commented on YARN-4705: -------------------------------------- stack attached. Looking at the code, I'm not sure what the retry policy here should be. FNFE, auth failures? recoverable or not? it's hard to predict. {code} 2016-02-19 18:46:32,641 [EntityLogPluginWorker #1] WARN org.apache.hadoop.fs.FSInputChecker (ChecksumFileSystem.java:<init>(157)) - Problem opening checksum file: file:/Users/stevel/spark-timeline-integration/target/tmp/ats/active/application_1111_0000/appattempt_1111_0000_000000/summarylog-appattempt_1111_0000_000000.
