Subject [jira] [Commented] (SPARK-2655) Change the default logging level to WARN
Date Sat, 02 Aug 2014 23:06:11 GMT


Sean Owen commented on SPARK-2655:

(Are you proposing PRs for any of these JIRAs?)
Disabling INFO seems a bit excessive though some particular classes are noisy and might do
with a default of WARN.

> The current logging level INFO is pretty noisy, reduce these unnecessary logging will
provide better experience for users.
> Currently, Spark is march stable and nature than before, so user will not need those
much logging in normal cases. But some high level information will be helpful, such as messages
about job and tasks progress, we could changes these important logging into WARN level as
an hack, otherwise will need to change all other logging into level DEBUG.
> PS: it's better to have one line progress logging in terminal (also in title).
