Tao, If I am running on the command line the following command >bin/kafka-run-class.sh kafka.tools.TestEndToEndLatency 192.168.1.3:9092 192.168.1.1:2181 speedx3 50000000 100 1 -Xmx1024m
It promped that it is not correct. So where should I put the -Xmx1024m option? Thanks. On Wed, Jul 15, 2015 at 3:44 AM, Tao Feng <fengta...@gmail.com> wrote: > (Please correct me if I am wrong.)
