Subject Run multiple HDFS instances
Date Thu, 18 Apr 2013 09:04:32 GMT
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
