这个问题让我郁闷了很久 就是启动不了
-ThinkPad-X200:/opt/cm-5.0.0$ sudo /opt/cm-5.0.0/etc/init.d/cloudera-scm-server start
Starting cloudera-scm-server: * Couldn't start cloudera-scm-server
后来发现 下载完mysqlconnector 直接解压产生了hbm.xml文件，污染了hibernate框架加载
mysql-connector-java-5.1.30 validation-api-1.1.0.Final.jar
commons-logging-1.1.1.jar jackson-dataformat-csv-2.1.0.jar mysql-connector-java-5.1.30-bin.jar velocity-1.7.jar
一定要注意
find -name '*.xml'
