RE: Pig cannot resolve BamUDFLoader
What is the .bam file your are trying to load as and how is it  generated?

What does your pig script look like? That will help answer your question.

Subject: Pig cannot resolve BamUDFLoader

Hi Everyone,

I have absolutely no experience with Pig and limited experience with hadoop, so please bear with me. We built a small hadoop cluster for experimental purposes and installed pig with all listed dependencies. I made sure that all of the jars are in CLASSPATH and env variables are defined as docuemtned, but still getting the following error:

2013-04-22 16:50:08,770 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1070: Could not resolve BamUDFLoader using imports: [, org.apache.pig.builtin., org.apache.pig.impl.builtin.]

And this is the command we are running:

pig -param inputfile=./bowtie_sorted.bam -param outputfile=hadoop_bam.pileup -param pparallel=1 ${SEQPIG_HOME}/scripts/pileup.pig

My google search for this error or "BamUDFLoader" alone did not return anything useful. Which jar is supposed to provide this function? Any suggestions will be appreciated.

Thanks a lot in advance!
-Mehmet
