Josh Elser commented on ACCUMULO-2052:
--------------------------------------
Agreed -- In the HA Namenode case, you actually wouldn't have to do anything
(Accumulo or Hadoop). If you haven't configured Accumulo otherwise with
instance.dfs.uri, you'll automatically get the nameservice URI, which means you
don't have to do anything if a namenode fails over.
> Recommend using viewfs:// or HA Namenode

> Issue Type: Sub-task
> Components: master, tserver

> Fix For: 1.6.0

> Given that recovering from a failed namenode in 1.6 could be tricky (see
> ACCUMULO-1832). I think we should recommend using viewfs:// or HA namenodes
> in documentation. Using either of these approaches, there would be no need
> to rewrite uris in Accumulo. Only hadoop config would need to be changed if
> the namenode is moved.
