Comment on Working with Hadoop: My first MapReduce App by Maha Alabduljalil

another question …

What happens if you write: return splits.toArray() ;
instead of : return splits.toArray(new PrimeInputSplit[splits.size()]);

in the getSplits of the PrimeTextInputSplit class ?

Thanks a lot Although, I’m a little suspicious about:

//add last split, with remainder if any // Is there an error?? start+remainder
splits.add(new PrimeInputSplit(startingNumberInSplit,
endingNumberInSplit + remainderInLastSplit));

because endingNumerInSplit is already updated in the loop above it to be starting+NumInSplit … So that line should be:

splits.add(new PrimeInputSplit(startingNumberInSplit,
startingNumberInSplit + remainderInLastSplit));

Right?

Anyways, thanks again, I’ve been looking for this for days !!

Comment on Interesting “bloated java” Article by athomas

I was spoiled for awhile when I did Python for over 4 years. Then I got another job doing Java. It was horrible. Had to write far too many more lines of code to accomplish the same tasks. Awful

Hi.. Nice article.. I have a few doubts, in PrimeTestInputFormat.java, there is a int numSplits argument. what factor decides the value of the argument ?

Comment on Firemote project is finally public by Alaa

Hi David,

There are some papers out there. Not sure what specifically you’re looking for but field trials are documented for different types of fire detection systems(sensor systems have probably the least coverage because they’re the newest). We’re hoping to publish our approach some time soon. Email me offline if you’d like to talk.

Alaa.

Hello,
The company I work for is specifying, at the customer’s request, a distributed network fire sensor system for parts of a Greek forest. I am looking for evidence that such a system does indeed help in detecting forest fires. Can you point me to field trials and any papers describing such work?
Thank you for any attention you can give me.
