Hello,
Does anyone have notes on how to build Hadoop on a EC2 instance based on
the trunk? I am trying to use http://wiki.apache.org/hadoop/HowToContribute.
I used a micro ec2 instance and when I ran mvn compile, some test ran out
of memory and the build failed. I then tried a large ec2 instan
I have biuld a distribute index using the source code of
hadoop/contrib/index，but I found that when the input files become big（such
as one file is 16G）,the OOM exception will be throwed .The cause is that: in
combiner ,"writer.addIndexNoOptimize()",this use much memory cause to OOM,
it's the Lucene
