      Description

      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.
