Bibin A Chundatt commented on YARN-8898:
----------------------------------------

[~subru] are you suggesting add the _ApplicationSubmissionContext_ to 
_ApplicationHomeSubCluster_ and then  write to 2 different znodes/tables at 
store side ??

If you are suggesting same znode then might not be feasible.We are writing only 
subClusterIdProto to *APPLICATION/APPID* node.
{code:java}
    String appZNode = getNodePath(appsZNode, appId.toString());
    SubClusterIdProto proto =
        ((SubClusterIdPBImpl)subClusterId).getProto();
    byte[] data = proto.toByteArray();
    put(appZNode, data, update);
{code}

This is not extendable rt ?? Unfortunately we didnt write 
ApplicationHomeSubCluster.getProto.getBytes to znode :(
