-------------------------------------

             Summary: ZK logging is oververbose, can cause oom in tests
                 Key: BOOKKEEPER-684
                 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-684
             Project: Bookkeeper
          Issue Type: Bug
            Reporter: Ivan Kelly
            Priority: Trivial
             Fix For: 4.2.2


Some tests, GcLedgerTests for example, create a lot of ledgers (30k) which 
causes a lot of zk writes. This causes a lot of zk logging, which can fill the 
log buffer and cause an oom when you're running with very little memory.

Fix is trivial. zk should be set to only log at error level in log4j.properties.
