Is there any tips or usage examples (e.g. sample codes)?
well,i guess i got the answer.First hadoop use tcp,so will not occur
situations like reaultBody_by_threadB,callId_by_threadB;Second,the server has
been synchronied on the response queue when the responder send response
messages ,and for one call each time.Since the clients use the same

Hey,
Did you update the config directory(ies) with defaults from the new
release ?
config/hadoop-default.xml may have been modified with new settings

If you do this on your own, please contribute it back to Hadoop! *smile*

Just one more thing to ask..

Hi Jeff,
I've built two public 0.17.0 AMIs (32-bit and 64-bit), so you should
be able to use the 0.17 scripts to launch them now.
Cheers,

Hi,

Any ideas why?

Also, if one source of the join is small enough to fit in memory, you can
build an in-memory table and do the map-side join on unsorted data.

In yesterday's user group meeting, Ted asked if the new sort function
in the MapReduce implementation was stable, since typically quicksort
is not stable for efficient implementations. Assuming Hadoop is using

I'm trying to figure out why I need to use HOD vs. trying to run multiple jobs

Hi,
we wrote a program that uses a Writer to append keys and values to a file.
If we do an fsck during these writing the opened files are reported as corrupt

the file size is zero until they are closed. On the other side if

Hello all,
I'm trying to stream a little python script on my small hadoop
cluster, and it doesn't work like I thought it would.
The script looks something like
#!/usr/bin/env python

dostuff
where mylib is a small python library that I want included, and I
launch the whole thing
The first case sounds like HADOOP-2703.
