Hi,

java.lang.NoClassDefFoundError:
DataJoinMapperBase is not in the JoinHadoop.jar.
When I add it and related classes to JoinHadoop.jar, it works!
(although I got an IOException at reduce stage... maybe I should check the
code or input files)
thanks!

the Mapper configure or setup function using
File f1 = new File(file1name);
File f2 = new File(file2name);
Cause I am not 100% sure how does distributed cached

That was one of the things I had asked.
ulimit -a says it all.

This also indicates that your datanodes are more full than they should be.
Try deleting unnecessary blocks.
