------------------------------------
Component/s: fs
> 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
> Components: fs
> Reporter: Karen Coppage
> Priority: Minor
>
> 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)
