When I try to run a hdfs api program I get connection refused. However,
hadoop fs -ls and other commands work fine. I don't see anything wrong in
the application web ui.
[mohit@localhost eg]$ hadoop jar hadoop-labs-0.0.1-SNAPSHOT.jar
org.hadoop.qstride.lab.eg.HelloWorld
hdfs://localhost/user/mohi
Hi,
I'm running Hadoop 2.2.0, and occasionally some my MR jobs failed due to
below error.
The issue is the job was running on 2014-06-24, but the path was pointed to
/2014/06/01, do you guys know what's going on here?

Please send email to user-unsubscr...@hadoop.apache.org
Cheers

I have a scenario.
Output from previous job1 is http://pastebin.com/ADa8fTGB.
In next job2 I need to get/find i key having maximum value.
eg i=3, 3 keys having maximum value.

How to approach this.
Should we calculated max() in job2 mapper as there will be unique

Cluster-running upgrade is only supported after 2.4, that is, upgrade from 2.4
to 2.4+ is supported; upgrading from 2.2 to 2
