Ekanth S commented on HDFS-13653:
---------------------------------

The patch [^HDFS-13653.001.patch] handles backwards compatibility with current 
configs that use it as global value and gives preference to a specific 
configuration if present.

> Currently the dfs.client.failover.random.order is applied globally. If we 
> have a combination of router and non-router nameservice, the random order 
> should ideally be enabled only for the router based nameservice. This Jira is 
> to make this configuration per-nameservice so that this can be configured 
> independently for each nameservice.
