             Summary: Existing Slider apps fail to start with hdfs path errors when NameNode HA is enabled
                 Key: SLIDER-903
                 URL: https://issues.apache.org/jira/browse/SLIDER-903
             Project: Slider
          Issue Type: Bug
          Components: core
    Affects Versions: Slider 0.80
            Reporter: Gour Saha


All hdfs paths in internal.json and app_config.json had to be modified from {{hdfs://<nn_host:nn_port>/user/yarn/...}} to {{hdfs://<cluster_name>/user/yarn/...}}.

For e.g. references to {{hdfs://c6401.ambari.apache.org:8020/user/yarn/.slider/cluster/hbase_demo/app_config.json}} had to be modified to {{hdfs://mycluster/user/yarn/.slider/cluster/hbase_demo/app_config.json}}, where mycluster is the cluster name provided during NN HA.

This needs to be handled in a way, such that Slider apps continue to run post NN HA enabled.
