Hi Habeeb,
Try to turn off the safemode with the following command
bin/hadoop dfsadmin -safemode leave
as safemode is on and no modifications can be done to the fs or
blocks.[read only mode of the HDFS] and restart.
Hope you find this useful.
Thank You.

Hi,
it may be a stupid question, but in my application I could do without sort
by keys. If only reducers could be told to start their work on the first
maps that they see, my processing would begin to show results much earlier,
before all the mappers are done. Now, eventually, all mappers will
Hi,
The record delimiter is not to be specified while copying the file, but
when you run the map reduce job. Just copy the file and specify the
delimiter at the time of the job run.

Mark,
Instead of the mapper writing intermediate data that usually goes to the
reducers, the mapper can write directly to HDFS if the job is map-only.

Mapper-Only Jobs
Often, you may want to process input data using a

Thanks for your response.

All hadoop contributors/experts,
I am trying to simulate split brain in our installation. There are a few
things we want to know
1. Does data corruption happen?
2. If Yes in #1, how to recover from it.
3. What are the corrective steps to take in this situation e.g. killing one
