This is the part of mapper code:
.
.
.
.
DatastoreService ds = DatastoreServiceFactory.getDatastoreService();
KeyRange range = new KeyRange(p.getParent(), p.getKind(),
p.getKey().getId(), p.getKey().getId());
ds.allocateIdRange(range);
.
.
.

Any help would be greatly appreciated :)

[appengine-java] /mapreduce/mapperCallback - RuntimeException: Couldn't find MR with job ID

[Santosh kumar]

Hi,

I had a question in the last year june,
regarding:
/mapreduce/mapperCallback java.lang.RuntimeException: Couldn't find MR with
job ID

http://groups.google.com/group/google-appengine-java/browse_thread/thread/2df5d998f13c14c8?pli=1

For the above said reason i stopped using mapreduce. But now i started
using it once again, but i am facing the same exception !!!

After running the mapper, exception is thrown, and mapper is not stopped.
This happens sometimes no matter the task of the mapper is done or not.

Why this exception is thrown ? how to handle it ?

Can anyone point out where is the problem. Thanks in advance.
