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
