Hi Niranjan,
Every thing looks ok as per the info you have given. Can you check
in the job.xml file whether these child opts reflecting or any thing else is
overwriting this config.

and also can you tell me which
Hi Koji,
This was on CHD3U1. For the record I had the dfs.name.dir.restore which

Harsh,
Are you mentioning about the 0.23 or pre-0.23 release? The OP was about
0.23 release. Were you able to start some daemons in Eclipse and submit a
job?
Some time back I posted a query [1] about setting 0.23 in Eclipse and the
response was that no one might have tried it. I gave it up after
Hi
The system we are going to work on will receive 50mio+ new datarecords
every day. We need to keep a history of 2 years of data (thats 35+
billion datarecords in the storage all in all), and that basically means
that we also need to delete 50mio+ datarecords every day, or e.g. 1,5
billion e
Per Seffensen,
I would urge you to step away from the keyboard and rethink your design.
It sounds like you want to replicate a date partition model similar to what you
would do if you were attempting this with HBase.
HBase is not a relational database and you have a different way of doing things
Thanks for your reply!

Will do :-) But would actually still like to receive answers for my
questions - just pretend that my ideas are not so stupid and let me know
if it can be done

These are indeed the actual settings I copied over from the job.xml.

Thanks.
Hi -
We have two namenodes set up at our company, say:

I'm hoping there is a better answer, but I'm thinking you could load
another configuration file (with B.company in it) using Configuration,
grab a FileSystem obj with that and then go forward. Seems like some
unnecessary overhead though.
Thanks,

Can you show your code here ? What URL protocol are you using ?
I’m guess I’m being very naïve (and relatively new to HDFS). I can’t show too
much code, but basically, I’d like to do:
Path myPath = new Path(“hdfs://A.mycompany.com//some-dir”);
Where Path is a hadoop fs path. I think I can take
Hi Bai,
I'm moving this over to scm-us...@cloudera.org as that's a more
appropriate list. (common-user bcced).
I assume by "Cloudera Free" you mean Coudera Manager Free Edition?
You should be able to run a job in the same way that do on any other
Hadoop cluster. The only caveat is that you first

Hi,
Does anyone know any discussion in Apache Hadoop regarding the claim by
Parrallel Iron with their patent against use of HDFS?
Thanks in advance.

Isn't that old news?

Yes, I wondered whether there was any update since or previous

You could just look at the archives:

It is also indexed by all search engines.

Can you see any errors in the logs? Typically this happens when you have no

Check the 'nodes' link and then RM logs.

Hi guys !
I want to see the behavior of a single node of Hadoop cluster when IO
intensive / CPU intensive workload and mix of both is submitted to the
single node alone.
These workloads must stress the nodes.
I see that TestDFSIO benchmark is good for IO intensive workload.
