HadoopConfigurationBuilder assumes that a Hadoop cluster has both a namenode
and a jobtracker
---------------------------------------------------------------------------------------------
Key: WHIRR-571
URL: https://issues.apache.org/jira/browse/WHIRR-571
Project: Whirr
Issue Type: Bug
Components: service/hadoop
Affects Versions: 0.7.1
Reporter: Zuocheng Ren
Priority: Trivial
I removed hadoop-jobtracker and hadoop-tasktracker from
whirr.instance-templates in hbase-ec2.properties.
Then I got the following error when trying to start a cluster.
Am I doing anything wrong by removing the tracker from instance templates?
Or is this an issue or not?
If it is not an issue, am I be able to start hbase without starting the
jobtracker and tasktracker? What is the right way to do it?
