something is wrong with your name-resolution. If you look at the error
message, it says you are trying to connect to 127.0.0.1 instead of the
remote host.

I need to do search files in distributed database Storage.. I need to

different search exploration techniques. Shall I use HBase for this?? Can
you suggest something for implementing this??

Thanks
Going through cloudera search functionality would be useful for you. Have a
look at solr also you can integrate it with hadoop

Hi,
I am trying to run Contrail on Hadoop and it starts ok, but after some time
throws an error. Some java class can't convert a string to float because
there is a comma.
I think the problem is not at contrail code. Maybe the location of my
timezone? Does anyone already passed through this?

Thank you Shekhar, Harsh. I will follow and try to implement your
suggestions. I appreciate the help.

This is usually a String.format() problem, when the developer was
using an English locale and was not aware of the fact, that
String.format is locale dependent.
Try this:

I don't know anything about contrail, I believe it is a better idea,
to ask on their mailing list for help:

I just noticed the job status for MR jobs tends to show 0's in the Map and
Reduce columns but actually shows the totals correctly.
I am not sure exactly when this started happening, but this cluster was
upgraded from Hadoop 1.0.4 to 1.1.2 and now to 1.2.1. It definitely worked
fine on 1.0.4, but
Hi,
I reported this issue in MAPREDUCE-5376
(https://issues.apache.org/jira/browse/MAPREDUCE-5376) and attached a
patch.
But it is not fixed by the current release.

Keep in mind that there are 2 flavors of Hadoop: the older one without HA
and the new one with it. Anyway, have you seen the following?

Thanks all for the JIRA links.
It appears this was 'fixed' in an older JIRA... but looking at the source
in my 1.2.1 webapps directory, it definitely is not fixed!
I'll comment on the new JIRA.

Hello Tomasz,
Just to add,
Although it says *masters*, the */conf/masters* actually specifies the
machine where *SecondaryNameNode* will run. Master daemons run on the

Adam's response makes more sense to me to offline replicate generated data
from one cluster to another across data centers.
Not sure if configurable block placement block placement policy is

Under replicated blocks are also consistent from a consumers point. Care of

No.
There are several ways a user can impersonate another user if you do
not use strong authentication (i.e. kerberos). Some ways are
implemented with that intention, for users who don't want any
authentication.
