Guys,
I was using hadoop eclipse plugin on hadoop 0.20.2 cluster..
It was working fine for me.
I was using Eclipse SDK Helios 3.6.2 with the plugin
"hadoop-eclipse-plugin-0.20.3-SNAPSHOT.jar" downloaded from JIRA
MAPREDUCE-1280

Now for Hbase installation.. I had to use hadoop-0.20-append compiled
jars..and I had to replace the old jar files with new 0.20-append compiled
jar files..
But now after replacing .. my hadoop eclipse plugin is not working well for
me.
Whenever I am trying to connect to my hadoop master node from that and try
to see DFS locations..
it is giving me the following error:
*
Error : Protocol org.apache.hadoop.hdfs.protocol.clientprotocol version
mismatch (client 41 server 43)*

However the hadoop cluster is working fine if I go directly on hadoop
namenode use hadoop commands..
I can add files to HDFS.. run jobs from there.. HDFS web console and
Map-Reduce web console are also working fine. but not able to use my
previous hadoop eclipse plugin.

Any suggestions or help for this issue ?

Thanks,
Praveenesh

Hadoop eclipse plugin also uses hadoop-core.jar file communicate to the
hadoop cluster. For this it needs to have same version of hadoop-core.jar
for client as well as server(hadoop cluster).

Update the hadoop eclipse plugin for your eclipse which is provided with
hadoop-0.20-append release, it will work fine.

I followed michael noll's tutorial for making hadoop-0-20-append jars..

http://www.michael-noll.com/blog/2011/04/14/building-an-hadoop-0-20-x-version-for-hbase-0-90-2/

After following the article.. we get 5 jar files which we need to replace it
from hadoop.0.20.2 jar file.
There is no jar file for hadoop-eclipse plugin..that I can see in my
repository if I follow that tutorial.

Also the hadoop-plugin I am using..has no info on JIRA MAPREDUCE-1280
regarding whether it is compatible with hadoop-0.20-append.

Does anyone else. faced this kind of issue ???

Every time when hadoop builds, it also builds the hadoop eclipse plug-in
using the latest hadoop core jar. In your case eclipse plug-in contains the
other version jar and cluster is running with other version. That's why it
is giving the version mismatch error.

 

Just replace the hadoop-core jar in your eclipse plug-in with the jar
whatever the hadoop cluster is using  and check.

Hi,

I am using Eclipse Helios Service Release 2.
I encountered a similar problem (map/reduce perspective failed to load) when
upgrading eclipse plugin from 0.20.2 to 0.20.3-append version.

I compared the source code of eclipse plugin and found only a few
difference. I tried to revert the differences one by one to see if it can
work.
What surprised me was that when I only reverted the jar name from
"hadoop-0.20.3-eclipse-plugin.jar" to "hadoop-0.20.2-eclipse-plugin.jar", it
worked in eclipse.

Hi,

Our hadoop version was built on 0.20-append with a few patches.
However, I didn't see big differences in eclipse-plugin.
