Hello,
I am trying to deploy a Hadoop cluster with 3 nodes using Ambari.
This is my set-up:
HDFS
NameNode: NodeA
SecondaryNameNode: NodeA
DataNodes: 2 hosts
MapReduce
JobTracker: NodeA
TaskTracker: 2 hosts
Nagios
Server: NodeA
Ganglia
Server: NodeA
However, after clicking the deploy button, the process seems to be stuck.
I got something like this on the server log:
\"component\":\"JOBTRACKER\",\"hostName\":\"Crawler51\",\"serviceId\":\"MAPREDUCE\",\"isInstalled\":false},{\"display_name\":\"Nagios
Server\",\"component\":\"NAGIOS_SERVER\",\"hostName\":\"Crawler51\",\"serviceId\":\"NAGIOS\",\"isInstalled\":false},{\"display_name\":\"Ganglia
Collector\",\"component\":\"GANGLIA_SERVER\",\"hostName\":\"Crawler51\",\"serviceId\":\"GANGLIA\",\"isInstalled\":false}],\"slaveComponentHosts\":[{\"componentName\":\"DATANODE\",\"displayName\":\"DataNode\",\"hosts\":[{\"hostName\":\"Crawler52\",\"group\":\"Default\",\"isInstalled\":false},{\"hostName\":\"Crawler53\",\"group\":\"Default\",\"isInstalled\":false}]},{\"componentName\":\"TASKTRACKER\",\"displayName\":\"TaskTracker\",\"hosts\":[{\"hostName\":\"Crawler52\",\"group\":\"Default\",\"isInstalled\":false},{\"hostName\":\"Crawler53\",\"group\":\"Default\",\"isInstalled\":false}]},{\"componentName\":\"CLIENT\",\"displayName\":\"client\",\"hosts\":[{\"hostName\":\"Crawler52\",\"group\":\"Default\",\"isInstalled\":false},{\"hostName\":\"Crawler53\",\"group\":\"Default\",\"isInstalled\":false}]}]},\"AddHost\":{},\"AddService\":{}}}"}
So after waiting for hours and hours, I tried to do it all over again.
First I did a reset (ambari-server reset) on the Ambari host
then did everything from scratch. When I reach the Deploy part, this
time, I get a message that a cluster with the same name already exists.
Here are my questions:
1. What to do with the stuck deploy?
2. How to remove the cluster that supposedly exist already? When I log
in to Ambari, I am redirected to the install wizard.
Thanks.
