Would it be possible to install two version of Hadoop on the same cluster?
Hi Everyone
Would it be possible to install two version of Hadoop on the same
cluster?and running at the same time?
I have installed CDH4 on my cluster,but for the test requirements we
need hadoop
v0.20.2 at the same time
Is there any solution for my situation?

Agree with Chris.. We were testing multiple distributions of hadoop on the
same cluster sharing tfhe space but using different dir structure. It
shouldn't be an issue. But make sure to stop/kill the relared java
processes of one version/distro.. If not you end up getting the 'unable to
bind port' exceptions ..

Alternatively just configure each installation to use different directories
for NameNode and DataNode data so that formatting one does not mess up the
other.

In this case,you need to handle the HDFS version issue when you switch from A to B or B to A.

If you are planning to take measurements when both are running they won't be representative of either one. For instance, your network could look like a bottleneck when both are running even if it could handle each one on its own. Datanodes that would have had capacity allowing local processing might not have capacity because they are servicing the other cluster etc. I would test them one at a time.

Re: Would it be possible to install two version of Hadoop on the same cluster?
Posted by Geelong Yao <ge...@gmail.com>.
Hi Chris
You are correct.
When I am testing the performance of version A, I would shut-down the
version B
But I do not know whether I could install two version of hadoop at the same
cluster

If you are planning to take measurements when both are running they
won't be representative of either one. For instance, your network could
look like a bottleneck when both are running even if it could handle
each one on its own. Datanodes that would have had capacity allowing
local processing might not have capacity because they are servicing the
other cluster etc. I would test them one at a time.
