Hi, I've got a question regarding hadoop configuration. Is it possible to pass configuration parameters on job start up? Something like that:
hadoop -HADOOP_HEAPSIZE=4G jar some.jar some.class.to.execute param1 param2 Or do I have to restart the hadoop cluster every time I want to change something even if it is just for a specific job or workflow? We have some jobs running which needs a lot of time and we want to start another one with a slightly different configuration because it needs more memory to finish. We are using CDH3. Greetings, Mat
