Membase Java Load Generator Problem

Hi,

I am trying to run Java Load Generator provided in membase documentation.

Firstly, I modified workloadb file and mentioned membase server address into it.

WORKLOADB FILE CONTENT :

db=com.yahoo.ycsb.db.SpymemcachedClient

memcached.address=10.72.45.165

memcached.port=11211

slaveaddress=10.112.83.64

histogram.buckets=20

exportfile=results.txt

recordcount=200000

operationcount=500000

workload=com.yahoo.ycsb.workloads.MemcachedCoreWorkload

#insertstart=200000

readallfields=true

insertproportion=0

readproportion=0.95

updateproportion=0

scanproportion=0

#memaddproportion=0.05

memgetproportion=0.100

#memsetproportion=0.25

memupdateproportion=0.0

#memappendproportion=0.05

#memprependproportion=0.05

#memreplaceproportion=0.05

#memcasproportion=0.05

valuelength=2048

workingset=100000

churndelta=100000

printstatsinterval=5

requestdistribution=zipfian

threadcount=4

Then, I build whole load generator project by using command : ant decompile-memcached

And Tried to load data using command :

 java -cp build/ycsb.jar:lib/memcached-2.5-14-g3b3b3c8.jar:lib/jackson-core-asl-1.5.2.jar:lib/jackson-mapper-asl-1.5.2.jar:lib/slf4j-api-1.6.1.jar:lib/slf4j-simple-1.6.1.jar:lib/memcached-2.5-27-gc7bc636-sources.jar:lib/memcached-2.6.jar com.yahoo.ycsb.LoadGenerator -load -P worloads/workloadb

After issuing this command, I got the terminal output :

 0 sec:  0 operations; 0 ops/sec

Can anyone please point out the mistake ? I have three membase servers running in cluster. I am not able to understand what does this error mean.
