What version of hadoop are you using? I believe this problem got resolved a
while back (and 0.11.x has the fix).
Thanks

Hi!
I tried to run wordcount example with a 1,9 GB input file, on 6 Nodes.
Hadoop has split the job in: 31 maps and one reduce.
All the maps fail with this stacktrace
java.lang.NullPointerException

org.apache.hadoop.io.SequenceFile$Sorter$MergeQueue.merge(SequenceFile.jav

I tried the example with hadoop 0.10.1 and nightly build
hadoop-2007-02-02 (with the same input), i got the same exception.
Any help will be appreciated.
Thanks!
