Description
When hbase shell with HBase 2.5.2 started there is too much logging of zk connection realated, classpaths etc. Even though we enabled ERROR log level for zookeeper package.

Better to change the org.apache.hadoop.hbase.zookeeper package log level to error.
# Set logging level to avoid verboseness
org.apache.logging.log4j.core.config.Configurator.setAllLevels('org.apache.zookeeper', log_level)
org.apache.logging.log4j.core.config.Configurator.setAllLevels('org.apache.hadoop', log_level)
org.apache.logging.log4j.core.config.Configurator.setAllLevels('org.apache.hadoop.hbase.zookeeper', log_level)
