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
