if you want work with HA, yes , all these configuration needed.
--Send from my Sony mobile.
I'm a hadoop n00b, and I had recently upgraded from hadoop 0.20.2 to
hadoop 2 (chd-4.2.1)
For a client configuration to connect to the hadoop cluster, in the
earlier 0.20.2 case,
I had to specify only the,
fs.default.name and mapred.job.tracker config parameters.
But now, with the HA configuration of hadoop 2. I have a lot of
parameters in my client configuration.
My Question is, do I really need all these configurations in the client?
I'm looking for minimalist client configuration that would let me work
with the hadoop cluster in HA mode.
Thanks in advance.
