spark + drools
An example to run drools inside 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 1. zookeeper info 2. rules xls file 3. open tsdb url Comment out lines 94 in SepsisStream.scala, if you do not have opentsdb setup. Comment out lines 69 & 80 if you do not have HBase setup 4. Toggle lines 40 & 41 in SepsisStream.scala to run in local mode 5. The program generates sample data using a queueRDD To Run: mvn package If using HBase, create the test hbase table. Sample script in src/main/resource/create_hbase_table.rb start 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 /root/sprue-0.0.1-SNAPSHOT-jar-with-dependencies.jar sepsis.xls host.domain:2181 http://host.domain:4242/api/put The spark.executor.extraClassPath option is to work around a classpath issue in hbase on cdh5.4 The files option uploads the xls file to the spark executors
