cloudera manager 5.11.0 can not kill balancer process

[#1]

env:

cloudera manager 5.11.0

centos6.4   

cdh5.4.0

supervisor 3.0

balancer start with one_off_wrapper.sh

/bin/bash /usr/lib64/cmf/service/common/one_off_wrapper.sh /usr/lib64/cmf/service/hdfs/hdfs.sh balancer -threshold 1.0 -policy DataNode

When I stop balancer from website, the one_off_wrapper.sh killed, but java process remain.
