Request for information about the installer's new management nodes prompt.

Hi,

  Some time back I noticed a new prompt as I was installing a Trafodion
build:

Do you have a set of management nodes (Y/N), default is N:

  I was wondering how to appropriately answer this prompt to use the new
feature as it was intended.  For example, one cluster is using the HA
configuration and has only the HBase Master and HDFS Name Node processes
running on two nodes.  Several questions come to mind:

  1) Is the expectation those nodes will be entered at this prompt?

  2) Will entering a node on this line preclude certain processes from
running on that node, for example:
       a) Are mxosrvrs still started on those nodes?
       b) Are other Trafodion processes started on those nodes?

  3) Are there other considerations as to which nodes should or should not
be listed as management nodes?

  Any insights will be helpful and appreciated.

Thanks,
Dennis

Hi,

Amanda can correct me if I'm wrong but I think that this refers to
configurations where the distribution manager (Ambari or Cloudera) runs on
separate nodes in the cluster. That is, the nodes are part of the cluster
but is not used as edge nodes or storage nodes and, therefore, should not
have Trafodion services installed on them.
