Error in starting Pseudo-Distributed mode hadoop-0.19.2

[arvind subramanian <al...@gmail.com>]

Hi,

I am new to Hadoop, and am trying to get Hadoop started in
Pseudo-distributed mode  on   ubuntu jaunty.

In the archives I noticed that someone had a similar issue with
hadoop-0.20.0,   but the logs are different.

As in the quickstart  guide  (
http://hadoop.apache.org/common/docs/current/quickstart.html) , I
configured the xml files, and set up   passphraseless ssh


The output of  bin/hadoop namenode -format   is as follows :


09/08/13 23:52:49 INFO namenode.NameNode: STARTUP_MSG:
/************************************************************

The task-tracker log had the following error :

2009-08-13 23:11:55,884 ERROR org.apache.hadoop.mapred.TaskTracker: Can not
start task tracker because java.lang.RuntimeException: Not a host:port pair:

    at org.apache.hadoop.mapred.TaskTracker.<init>(TaskTracker.java:884)
    at org.apache.hadoop.mapred.TaskTracker.main(TaskTracker.java:2798)



After this point,  I could not acess  these in my browser  :

   - NameNode - http://localhost:50070/
   - JobTracker - http://localhost:50030/

If anyone could give an hint  on what could be the issue, it would be
great!

On another note, the quick start guide pointed to Cloudera's  distribution
of  Hadoop, and they have  debian package for ubuntu.
Is the development plan of Apache and Cloudera same? Do both ship the same
source release?


Cheers,
Arvind
