Cloudera Manage 5.7.0，cloudera-scm-agent无法启动，无法创建pidfile

Question

我启动了cloudera-scm-agent，但它失败了。我从/opt/cm-5.7.0/log/cloudera-scm-agent看到了日志。它说

/opt/cm-5.7.0/lib64/cmf/agent/build/env/lib/python2.6/site-packages/cmf-5.7.0-py2.6.egg/cmf/parcel.py:17: DeprecationWarning: the sets module is deprecated
  from sets import Set
[06/May/2016 12:24:12 +0000] 1589 MainThread agent        INFO     SCM Agent Version: 5.7.0
Unable to create the pidfile.

我该怎么办？请帮帮我！
