Hello Everyone,
I wanted to write a mr for hbase table.... there is a million record and i
wanted to write a Map reduce task to scan through it and then get the data
and find the 90the percentail of the result. It would be helpful if some
one
has a tried it before...
The thing which i am finding hard to understand and the question is:
How does MR get the input to the MR job, i mean how do i get the scanner
output to the MR job? i dont want to get a million row first and give it
back to the MR job but i needed to the region server's data directly go to
the MR job.
I saw the example @
http://www.nabble.com/Re:-Map-Reduce-over-HBase---sample-code-p18253120.html
but
still couldn't get it... :(.
Thanks in advance!
Regards,
