Greetings everyone, I'm learning a lot from reading all of the great questions and informative answers here on the Accumulo mailing list. Thus far I haven't come across a question similar to mine, nor a basic recommendation so here goes:
I'm looking for recommendations on process / component placement for a small Accumulo cluster serving a prototype. It will be scaled later, but for now I'm looking at a cluster with just 8 nodes. My current thought process has led me to the following server / process placement and I'm interested in feedback on it. zoo1, zoo2, zoo3: ZooKeeper servers, dual proc, 4 GB RAM (small servers) namenode, secnamenode: 16GB RAM, 4 cores each, with local and remote locations to store name data *** Can I place the Accumulo Master on the NameNode or Secondary NameNode? *** accdata1, accdata2, accdata3: 16GB RAM, 4 cores each, serving as HDFS DataNodes and Accumulo TabletServers each with 4 2TB JBOD disks for HDFS I'm thinking having the Accumulo Master on the NameNode will simplify cluster startup. Thoughts? Recommendations? Many thanks in advance, Terry
