Hello folks, I am trying to run multiple hadoop instances on the same cluster. I find it hard to share. First I try two instances, each of them run with the same master and slaves. Only one of them could work. I try to divide the cluster such that hadoop 1 use machine 0-9 and hadoop 2 uses machine 10-19. Still, only one of them could work. The HDFS of the second hadoop is working well, but start-mapred.sh will result in such exception "java.io.IOException: Connection reset by peer" in the log.
Any ideas on this or suggestion on how to run multiple hadoop instance on one cluster? I can total divide up the cluster such that different instances run on different set of machines. Thanks. -Gang
