This was corrected in Hadoop as per issue HADOOP-917, but I'm thinking some
code in Nutch might have to be changed also. I reported this issue (via mailing
list) a while ago and I'm glad it was fixed, but I have been purposely staying
with revision 495214 of trunk which seems to provide the best
stability/performance.

Subject: NPE while fetching
Hi,
I experience NPE while fetching I use Nutch trunk (a week ago) with Hadoop
0.11.1
java.lang.NullPointerException
at
org.apache.hadoop.io.SequenceFile$Sorter$MergeQueue.merge(SequenceFile.java:
2392)
at
org.apache.hadoop.io.SequenceFile$Sorter.merge(SequenceFile.java:2087)
at
org.apache.hadoop.mapred.MapTask$MapOutputBuffer.mergeParts(MapTask.java:498
)
at org.apache.hadoop.mapred.MapTask.run(MapTask.java:191)
at
org.apache.hadoop.mapred.TaskTracker$Child.main(TaskTracker.java:1372)
Any pointers to the cause?
Thanks,
Gal.-------------------------------------------------------------------------
