Getting GeoMesa 1.0 to work on Cloudera CDH 5.3 with Accumulo 1.6

Getting GeoMesa 1.0 to work on Cloudera CDH 5.3 with Accumulo 1.6

by @mikeatlas

Thanks goes out to @manasdebashiskar for helping me work through all these steps!

Getting GeoMesa to work on Accumulo 1.6 using Cloudera's CDH 5.3 is not any less easy than getting it to work on the officially supported version of Accumulo 1.5.x, but here are the steps you can take to make it happen.

First, you will need to setup an Accumulo 1.6 cluster in CDH. This requires you create a Zookeeper cluster, an HDFS cluster, and a Hadoop MapReduce cluster. For my purposes, I have the following setup (yours may differ as you see fit/need):

  • 3-host Zookeeper cluster, each running Ubuntu 12.02 (ami-018dd631 EC2 image) on t2.medium instances
