---------------------------------------
Summary: Downgrade stack trace on FS load from Warn to debug
Key: HADOOP-13323
URL: https://issues.apache.org/jira/browse/HADOOP-13323
Project: Hadoop Common
Issue Type: Improvement
Components: fs
Affects Versions: 2.7.3
Reporter: Steve Loughran
Assignee: Steve Loughran
Priority: Minor
HADOOP-12636 catches exceptions on FS creation, but prints a stack trace @ warn
every time..this is noisy and irrelevant if the installation doesn't need
connectivity to a specific filesystem or object store.
I propose: only printing the toString values of the exception chain @ warn; the
full stack comes out at debug.
We could some more tuning:
* have a specific log for this exception, which allows installations to turn
even the warnings off.
* add a link to a wiki page listing the dependencies of the shipped filesystems
