I think this is tricky in the sense if application returns with same exit
code then I am not sure if we differentiate between the two. But can be
used as defaults.

if it is not present in CLI then writing a simple wrapper around yarn -web
services will be a option. I think all your listed requirements will be
covered with web services though

Hi all,
Can someone tell me these:
1) which property in hadoop conf sets the time limit to consider a node as
dead?
2) after detecting a node as dead, after how much time does hadoop
replicates the block to another node?
3) if the dead node comes alive again, in how much time does hadoop

Hi,
It depends on which prop you are changing. To be safe, you need change it in
all nodes.

Hi,
I am working on a Hadoop cluster with 5 datanodes, and 1(NameNode+Job
Tracker) . If I would like to add a property to mapred-site.xml, then I
need to do that on all datanodes or doing it on JobTracker suffice?
I am using hadoop-0.20.203.0rc1 version of hadoop
Thanks
I recently blogged about it - hope it helps

Hi,
I suggest to read the chapter 2 of the book "Hadoop: the definitive guide".
In that chapter mapReduce is explained with a nice example, also there are
lines of code for map and reduce functions. Every phase of MapReduce is
explained in detail and there are examples of how mapReduce can be run
You can use maven to compile and package Hadoop and deploy it to one
cluster, then run it with script supplied by Hadoop.
And this tutorial for your reference

Did you installed Hive on your Hadoop cluster?
If yes, use Hive SQL may be simple and efficiency.
Otherwise, you can write a MapReduce program with
org.apache.hadoop.mapred.lib.MultiOuputFormat, and the output from the
Reducer can be written to more than one file.
