Yes, removing the biggest SPOF from the entire Accumulo architecture is
a good thing :)
The usage of it with Accumulo is, given all of my testing, completely
transparent. Once you configure HDFS correctly, there should be nothing
additional you have to do with Accumulo except make sure
instance.dfs.uri in accumulo.site.xml is up to date.

So I was looking into the software configuration for HA in regard to

So I was wondering, does Accumulo 1.5 benefit from the HA feature of
having a failover namenode?
