Gour Saha created SLIDER-903:
--------------------------------
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.
