An example to run drools with spark. 1. This tries to run the logic at http://www.mdcalc.com/sirs-sepsis-and-septic-shock-criteria/ 2. The relevant drools decision table file is in src/main/resources/sepsis.xls 3. The driver program takes three parameters a. zookeeper info b. rules xls file c. open tsdb url Comment out line 94 in SepsisStream.scala, if you do not have opentsdb setup Comment out lines 69 & 80 if you do not have HBase setup Toggle lines 40 & 41 in SepsisStream.scala to run in local mode 4. The program generates sample data using a queueRDD To Run (This has been tested on a CDH5.4 cluster): 1. mvn clean package 2. Create the hbase table. Sample script in src/main/resource/create_hbase_table.rb 3. Install opentsdb (http://opentsdb.net/docs/build/html/installation.html) 4. Start spark streaming using spark-submit --driver-java-options '-Dspark.executor.extraClassPath=/opt/cloudera/parcels/CDH/lib/hbase/lib/htrace-core-3.1.0-incubating.jar' --master yarn-client --files sepsis.xls --class com.cloudera.sprue.SepsisStream /path_to/sprue-0.0.1-SNAPSHOT-jar-with-dependencies.jar sepsis.xls zookeeper.host.domain:2181 http://opentsdb.host.domain:4242/api/put The spark.executor.extraClassPath option is a classpath workaround for spark on hbase on cdh5.4 The files option uploads the xls file to the spark executors
