Description

Many /var/log/message alerts we keyed off of previously are no longer working or valid. It appears that many hadoop 1.x terms such as jobtracker, tasktracker and templeton still exist, when Ambari is being used with hadoop 2.x.
I believe existing rules need to be modified for the following service name changes:
resourcemanager_process_down
resourcemanager_process_down_ok
resourcemanager_rpc_latency
resourcemanager_rpc_latency_ok
resourcemanager_cpu_utilization
resourcemanager_cpu_utilization_ok
nodemanagers_down
nodemanagers_down_ok
nodemanager_process_down
nodemanager_process_down_ok
webhcat_down
webhcat_down_ok

It also appears that existing messages are getting improperly matched as we see the following HADOOP_UNKNOWN_MSG in /var/log/messages:
Jul 15 10:36:34 pitH1 nagios[35331]: Warning: Hadoop: HADOOP_UNKNOWN_MSG# Event Host=pitH1.td.teradata.com Service Description=HDFS::Percent DataNodes with space available(WARNING), WARNING: total:6, affected:1
