On a K3S cluster, YCSB pod stops loading data to MongoDB pod early

36 views Asked by At

I have a 3 node K3S setup. I have a MongoDB statefulset with 3 replicas and a YCSB statefulset with one replica. I expose port 2222 on the YCSB so i can SSH onto it in order to load data onto my mongoDB.

When connected to the ycsb pod i run /root/ycsb-0.17.0/bin/ycsb load mongodb -s -P /root/ycsb-0.17.0/workloads/workloade -threads 8 -p recordcount=90000000 -p mongodb.url=mongodb://mongo-1.mongo.mongodb.svc.cluster.local:27017/ycsb?w=0 mongo-1 is the primary pod in the statefulset

the workload file is:

recordcount=1000
operationcount=1000
workload=site.ycsb.workloads.CoreWorkload

readallfields=true

readproportion=0
updateproportion=0
scanproportion=0.05
insertproportion=0.95

requestdistribution=zipfian

maxscanlength=100

scanlengthdistribution=uniform

This starts running and does write some records however it just goes back to console after 30/40 seconds with no error or success message:

I am new to using mongoDB and ycsb so any help would be appreciated!
