Installing GeoMesa on GeoServer
- Downloaded geoserver 2.5.2 war wget http://downloads.sourceforge.net/project/geoserver/GeoServer/2.5.2/geoserver-2.5.2-war.zip
- and the corresponding WPS plugin wget http://downloads.sourceforge.net/project/geoserver/GeoServer/2.5.2/extensions/geoserver-2.5.2-wps-plugin.zip
- Deployed war file to Tomcat_HOME/webapps folder and then copied WPS plugin jars over to WEB-INF/lib and checked to ensure permissions were good
- Download Accumulo 1.5.3 :: wget http://apache.go-parts.com/accumulo/1.5.3/accumulo-1.5.3-bin.tar.gz
- Download Scala 2.10 :: wget http://downloads.typesafe.com/scala/2.10.5/scala-2.10.5.tgz
- Download Kafka 2.10-0.8.2.1 (Kafka 0.8 install that corresponds to scala 2.10) http://ftp.wayne.edu/apache/kafka/0.8.2.1/kafka_2.10-0.8.2.1.tgz
