Hello friends,
I got the above error jobtarcker.info could only be replicated to 0 nodes
instead of 1
Tried different Solutions found on web :
* Formatted namenode
* removed tmp Folder
* cleaned uncessary logs just to have more space
But still no success . What other Solutions could it be ?
Can Setting up 2 datanodes on same machine be considered as
pseudo-distributed mode hadoop ?
Thanks,
Sindhu

Yes :)
Pseudo-distributed mode is such configuration when we have some Hadoop
environment on single computer.

You can perhaps start with a generic 4+4 configuration (which matches
your cores), and tune your way upwards or downwards from there based

May be u should give the complete path of jar file .
That is absolute path .

RE: Multiple DataNodes on a single machine .
Ist works fine 2 datanodes are up and running .
So i have 2 conf Folders conf and conf2 in hadoop-home .
If i have to set dfs.replication value to 3 - in
data nodes, you will most likely have two copies of the data in two
separate data nodes.

ok .thanks a lot that information .
As i said i am running 2 datanodes on same machine . so my haddop home has 2
conf folders .
conf and conf2 and in turn 2 hdfs-site.xml in both conf folders .
I guess dfs.replication value in hdfs-site.xml of conf folder should be 3 .
What should i have it in
This might be a dumb question but I really can't figure out how to reply to ANY
existing thread or post on the this hadoop mailing list . As far as I've
understood I can post threads to u...@hadoo.apache.org . but how to reply to
one particular post? There's no reply button, also reply-to or
subscribed to user mailing list ?
You can send email to user-subscr...@hadoop.apache.org .
Once you're a subscriber, you can reply to other users' emails.
