Can not launch TaskTracker (Error occurred during initialization of VM) #67
Comments
I modify the code, use config "mapred.mesos.executor.jvm.opts" take place of defaultOpts + taskTrackerJVMHeap as TaskTracker's $HADOOP_OPTS, then TT can launch successfully, but I think this is Not a good solution |
It'd be useful to know what memory configuration you'd set for the slots, and how many slots this task tracker had. I imagine the sum total in this case was too low and there's some tuning to be done? |
