Description

HadoopExecutors cleanup to only log at debug

HADOOP-16181 means that executor shutdown now logs @ info

this means every single hadoop fs command against s3 has four lines of information which is entirely irrelevant to all users.

We don't need to inflict this on anyone. Proposed: downgrade the logs to info. No need for tests
