Hello, I get this error when I try run my job:

I'm not sure where the start debugging. . .BspServiceWorker is hella big.  All 
input is welcome.  As I mentioned, I'm processing a sequenceFile that has Text 
keys and MapWritable Values.  I would like the vertices to have Text indices 
and MapWritable values.  (I'm not inserting any edges for the time being. . .I 
just want to see the file get split properly).  I have implemented custom input 
formats and record readers.  Thx
