Karen Coppage created HADOOP-17267: -------------------------------------- Summary: Add debug-level logs in Filesystem#close Key: HADOOP-17267 URL: https://issues.apache.org/jira/browse/HADOOP-17267 Project: Hadoop Common Issue Type: Improvement Reporter: Karen Coppage
HDFS reuses the same cached FileSystem object across the file system. If the client calls FileSystem.close(), closeAllForUgi(), or closeAll() (if it applies to the instance) anywhere in the system it purges the cache of that FS instance, and trying to use the instance results in an IOException: FileSystem closed. It would be a great help to clients to see where and when a given FS instance was closed. I.e. in close(), closeAllForUgi(), or closeAll(), it would be great to see a DEBUG-level log of * calling method name, class, file name/line number * FileSystem object's identity hash (FileSystem.close() only) -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
