cloudera-manager-el6-cm5.7.0版本启动Agent失败的问题解决

[Lihaifanzhou]

我们在部署完CDH 5.7.0和CM 5.7.0后，开始启动CM Agent，但是会出现下面的错误：
# cloudera-scm-agent start
Starting cloudera-scm-agent: [FAILED]


# cat /opt/cloudera-manager/cm-5.7.0/log/cloudera-scm-agent/cloudera-scm-agent.out
/opt/cloudera-manager/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
[10/Apr/2016 22:08:07 +0000] 5897 MainThread agent INFO SCM Agent Version: 5.7.0
Unable to create the pidfile.



解决办法:
mkdir /opt/cm-5.7.0/run/cloudera-scm-agent
chown -R cloudera-scm:cloudera-scm /opt/cm-5.7.0/run/cloudera-scm-agent


然后再重启CM Agent就可以了，不知道是不是CDH 5.7.0版本的问题。
