Kihwal Lee created HDFS-4714: -------------------------------- Summary: Support logging short messages in Namenode IPC server for configurable list of exception classes. Key: HDFS-4714 URL: https://issues.apache.org/jira/browse/HDFS-4714 Project: Hadoop HDFS Issue Type: Bug Components: namenode Affects Versions: 3.0.0, 0.23.7, 2.0.5-beta Reporter: Kihwal Lee
Namenode can slow down significantly if a rogue client/job issues massive number of requests that will fail. E.g. permission denied, quota overage, etc. The major contributing factor in slow down is the long namenode log message, which includes full stack trace. Previously similar issues involving safe mode and standby node have been addressed and we can extend it to suppress logging stack traces for configured list of exception classes. -- This message is automatically generated by JIRA.
