[佐々木貴志 <tsasaki609@xxxxxxxxx>]

Hello.

Our project team use GeoMesa 1.2.3 with Accumulo 1.7.2 on AWS EMR by BootStrapAction script which is /dist/tools/geomesa-tools-1.2.3-bin.tar.gz/emr4 in the release tarball.

We use AWS EMR release emr-4.7.0, Hadoop 2.7.2, ZooKeeper-Sandbox 3.4.8.

At bootstrapping, we encountered a few warning and error.
