Hi all, Can I run mutiple HDFS instances, that is, n seperate namenodes and n datanodes, on a single machine?
I've modified core-site.xml and hdfs-site.xml to avoid port and file conflicting between HDFSes, but when I started the second HDFS, I got the errors: Starting namenodes on [localhost] localhost: namenode running as process 20544. Stop it first. localhost: datanode running as process 20786. Stop it first. Starting secondary namenodes [0.0.0.0] 0.0.0.0: secondarynamenode running as process 21074. Stop it first. Is there a way to solve this? Thank you in advance, Lixiang Ao
