Subject error unsupported major.minor version 51.0
Date Mon, 16 Mar 2015 13:10:14 GMT
Hi all,

I am facing a strange problem. I tried to use Giraph to convert a graph
from a edge representation to adjacency list representation. However, I got
following error:

*Error: org/apache/giraph/bsp/BspOutputFormat: Unsupported major.minor
version 51.0*

I searched on google and found that it may be a problem with using
different versions of java. But after I set path of Java1.7 as $JAVA_HOME,
this error is still there.

Any advice would be greatly appreciated!
Best Regards.
