Java Null Pointer Exception

[ramsrivatsa]

When I execute TPCC in 3 servers with parameters sst_files_hard_limit =96; rlimit_nofile=1000000

and 2 clients with 4k warehouses altogether using these commands

./tpccbenchmark --nodes=172.151.21.7,172.151.30.255,172.151.20.156 --execute=true --warehouses=2000 --num-connections=300 --start-warehouse-id=1 --total-warehouses=4000

./tpccbenchmark --nodes=172.151.21.7,172.151.30.255,172.151.20.156 --execute=true --warehouses=2000 --num-connections=300 --start-warehouse-id=2001 --total-warehouses=4000

I get this error.
