I put my secondary namenode in the masters file for the first time with this latest Accumulo 1.4.2 cluster deployment so it would run as a Standby Accumulo Master which I read about in the User Guide. Recently had the Master lose its Zookeeper lock (network glitch, being researched), and was glad to see the secondary namenode Master process took over as it should.
But if my Namenode / Accumulo Master server goes down, I also lose the gc, monitor, and tracer processes as well. *Can I configure the secondary namenode in gc, tracer, and monitor files as well, or should they run on only one host at a time*? In this case, the GC also lost its Zookeeper lock, which resulted in a cluster with no GC running at all until I caught it. Thanks in advance.
