             Summary: LP Bug: 1391962 - need to make sure trafodion nodes are the same as hadoop distro nodes
                 Key: TRAFODION-754
                 URL: https://issues.apache.org/jira/browse/TRAFODION-754
             Project: Apache Trafodion
          Issue Type: Bug
          Components: installer
            Reporter: Marvin Anderson
            Assignee: Amanda Moran
            Priority: Critical


If the set of nodes trafodion is installed on is not the same as the set of node Hadoop is running on there will be problems.  One problem would be the copying of the hbase-trx.jar file, there might be other problems within DTM and other components.  Installer should add a check and appropriate error message if the trafodion set of nodes are not the same as the Hadoop distros nodes.

Alternatively, the trafodion installer could just pick up its list of nodes from the Hadoop distro but this might not be desirable in the future if a user wants to balance their node workload by installing trafodion on fewer or other node than the Hadoop distro.

Eventually Trafodion will need to support being installed on different or sub-set of the Hadoop nodes but for now, install needs to prevent it from happening.
