Esteban Gutierrez commented on HBASE-17007:
-------------------------------------------
We thought about removing only the classpath initially but that requires to
patch ZooKeeper to change the client logging level for ZK. Also ZooKeeper is
used by some coprocessors like Tephra and Phoenix and logs get polluted quite
easily due other tasks done by those CPs. There is another alternative and
that's removing the duplicated classpath from the logs by adding CLASSPATH to
the list of skipwords in ServerCommandLine but usually the CLASSPATH
environment string is shorter than java.class.path as reported by the jvm which
is what ZK si dumping. In a quick test the whole line with java.class.path is
63076 bytes long vs 14293 bytes long for the string that contains the CLASSPATH.
> Move ZooKeeper logging to its own log file
