----------------------------------
Hi [~tlipcon] , i would like to work on this issue.
Will soon update on this issue.
> Some usage of GetConf tool not compatible with federation
> ---------------------------------------------------------
>
> Key: HDFS-4202
> URL: https://issues.apache.org/jira/browse/HDFS-4202
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: federation, scripts
> Affects Versions: 3.0.0, 2.0.2-alpha
> Reporter: Todd Lipcon
> Priority: Minor
>
> In the start/stop scripts, we use the "getconf" tool to look up certain
> config keys to discover hosts we need to start/stop daemons on. However, some
> of these configs are optionally suffixed by a nameservice or
> nameservice.namenode identifier. In these cases, the start/stop scripts
> wouldn't correctly see the configs, and therefore would fail to start all the
> necessary daemons for the federated cluster.
