Test code for the paper "Efficient Event Correlation over Distributed Systems" [1]

1, The used METIS graph paritioner is avialble at (http://glaros.dtc.umn.edu/gkhome/metis/metis/download).

2, After exporting the jar file from the souce code, an sample of the job submission command is shown as below. Namely, besides the first four system parameters, there are 6 other parameters in our codes. There, "spark://taurusi5429:7077" is the sparkcontext, "hdfs://taurusi5429:54310/input/" is the file input path over HDFS, "32" is the number of executor cores, "Scm-250.csv.2" is the input event log, "0.1" is the value of \alpha and "0.5" is the value of \beta .

spark-submit \
--class RF_Graph \
--master spark://taurusi5429:7077 \
--executor-memory 30G \
ECA.jar \
spark://taurusi5429:7077 \
