Hi All,
I am getting Could not obtain block: blk_2706642997966533027_4482
file=/user/outputwc425729652_0/part-r-0
I checked the file is actually there.
What I should do?
Please help.

#1 Check CPU fan is working. A hot CPU can give flakey errorsespecially
during high CPU load.
#2 Do memtest on the machine. You might have a bad memory stick that is
getting hit (though I
would tend to think it would be a bit more random).
I've used memtest86 before to find such problems.

Mark,
Using EMR makes it very easy to start a cluster and add/reduce capacity as
and
Using hadoop-0.20
I'm doing custom input splits from a Lucene index.
I want to split the document ID's across N mappers (I'm testing the
scalabilty of the problem across 4 nodes and 8 cores).
So the key is the document# and they are not sequential.
At this point I'm using splits.add to add
EMR instances are started near each other. This increases the bandwidth
between nodes.
There may also be some enhancements in terms of access to the SAN that
supports EBS.
