Hello,

I tried running mongodb with ycsb and got it to work, however I am trying to use 0.17.0 and I'm getting this error when I try to run the workload.

java -cp /usr/local/ycsb-0.17.0/mongodb-binding/conf:/usr/local/ycsb-0.17.0/conf:/usr/local/ycsb-0.17.0/lib/htrace-core4-4.1.0-incubating.jar:/usr/local/ycsb-0.17.0/lib/jackson-mapper-asl-1.9.4.jar:/usr/local/ycsb-0.17.0/lib/core-0.17.0.jar:/usr/local/ycsb-0.17.0/lib/HdrHistogram-2.1.4.jar:/usr/local/ycsb-0.17.0/lib/jackson-core-asl-1.9.4.jar:/usr/local/ycsb-0.17.0/mongodb-binding/lib/mongodb-async-driver-2.0.1.jar:/usr/local/ycsb-0.17.0/mongodb-binding/lib/snappy-java-1.1.7.1.jar:/usr/local/ycsb-0.17.0/mongodb-binding/lib/logback-core-1.1.2.jar:/usr/local/ycsb-0.17.0/mongodb-binding/lib/mongodb-binding-0.17.0.jar:/usr/local/ycsb-0.17.0/mongodb-binding/lib/logback-classic-1.1.2.jar:/usr/local/ycsb-0.17.0/mongodb-binding/lib/slf4j-api-1.7.25.jar:/usr/local/ycsb-0.17.0/mongodb-binding/lib/mongo-java-driver-3.8.0.jar site.ycsb.Client -db site.ycsb.db.MongoDbClient -p mongodb.url=mongodb://130.127.134.13:27017/ycsb -s -P workload -threads 64 -target 2000 -t Command line: -db site.ycsb.db.MongoDbClient -p mongodb.url=mongodb://130.127.134.13:27017/ycsb -s -P workload -threads 64 -target 2000 -t YCSB Client 0.17.0

check your mongodb workload configuration, update ^workload line to:

workload=site.ycsb.workloads.CoreWorkload
