[jira] [Created] (WHIRR-663) HadoopProxy to support clusters
without a namenode
Steve Loughran created WHIRR-663:
------------------------------------
Summary: HadoopProxy to support clusters without a namenode
Key: WHIRR-663
URL: https://issues.apache.org/jira/browse/WHIRR-663
Project: Whirr
Issue Type: Improvement
Components: service/hadoop
Affects Versions: 0.8.1
Reporter: Steve Loughran
Priority: Minor
the Proxy setup code in {{HadoopProxy}} only works in clusters with namenodes, which works for Hadoop itself; services like Hama squeeze by.
Clusters without a NameNode can't, and are reduced to copy-and-paste work.
A good solution would be for core to have a proxy setup class; HadoopProxy would be just a NN-specific subclass
