Hi All,

I also just installed hadoop/RHIPE on my MAC 10.7.5 machine and I'm getting the exact same error when I run rhinit().

using:

• hadoop 2.2.0
  
• java version "1.6.0_65"
  
• R version 3.0.2
• protobuf version 2.4.1
  
• RHIPE version 73.1.5

Exact error message:

> library(Rhipe)

I'm new to java and RHIPE.  Can anyone parse this?

Thanks,

I've moved to osx recently so I can try and confirm if this is working. I'll get back to you tomorrow.

So i downloaded CDH4.5 from

http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/latest/CDH-Version-and-Packaging-Information/cdhvd_topic_3.html

My bash profile looks like

HADOOP=/usr/local/hadoop/
export HADOOP_LIBS=${HADOOP}/share/hadoop/mapreduce1/:${HADOOP}/share/hadoop/mapreduce1/lib
export HADOOP_LIBS=$HADOOP_LIBS:${HADOOP}/share/hadoop/hdfs/:${HADOOP}/share/hadoop/common/
export HADOOP_LIBS=$HADOOP_LIBS:${HADOOP}/share/hadoop/httpfs/:${HADOOP}/share/hadoop/tools/
export HADOOP_HOME=/usr/local/hadoop/
export HADOOP_CONF_DIR=/usr/local/conf.mango/hadoop

I used 0.73-3 (though -5 should work too) from http://ml.stat.purdue.edu/rhipebin/Rhipe_0.73.1-3.tar.gz. I have not tested this with Apache Hadoop (the rearch branch is being made to work with Apache Hadoop)



export RHIPE_USE_CDH4=yes

I was also getting similar issues when I was trying to use the hadoop2.2 version, but when try to use the earlier version it is working perfectly

[Ryan Ward Kelley]

Ok, thank you very much -- I will give this a try.

Just to be clear, you used a different version of hadoop from the link you provided and that worked.  Apache hadoop is not supported by RHIPE at this time.  Is this correct?

Thanks,

Ryan

[Saptarshi Guha]

Yes, we initially we tested on Apache, but to make it work with CDH4 i introduced a change which made it incompatible to Apache!

We have fixed this glitch but it is not released yet.

Does the website say to use Apache??? Thats needs to be changed asap.

Yes, please do test and reply here. I can help if you have issues.

Cheers

[Ryan Ward Kelley]

Oh, sorry.  I was using a book I down loaded: http://www.packtpub.com/big-data-analytics-with-r-and-hadoop/book

It's instructions say to use hadoop but it is a bit older.  I will switch to CDH4 and give it a try.

Thank you again,

Ryan

[Saptarshi Guha]

hmm, some tech books get outdated very quickly. The mailling list is fairly helpful.

[salah bensator]

I Have exactly the same problem. 

I didn't get it, you were able to fix it ? 

Is there a way to fix the problem without using CDH?
