I'm plagued with this error:
Retrying connect to server: localhost/127.0.0.1:9000.

I'm trying to set up hadoop on a new machine, just a basic pseudo-distributed setup.  I've done this quite a few times on other machines, but this time I'm kinda stuck.  I formatted the namenode without obvious errors and ran start-all.sh with no errors to stdout.  However, the logs are full of that error above and if I attempt to access hdfs (ala "hadoop fs -ls /") I get that error again.  Obviously, my core-site.xml sets fs.default.name to "hdfs://localhost:9000".

I assume something is wrong with /etc/hosts, but I'm not sure how to fix it.  If "hostname" returns X and "hostname -f" returns Y, then what are the corresponding entries in /etc/hosts?

Thanks for any help.

Hi Keith,

Does ping to localhost returns a reply? Try telneting to localhost 9000.

Thanks,
Anil

Hi Keith

Your NameNode is not up still. What does the NN logs say?

I got it.  The hadoop installation had been done by root (I can't claim credit for that thankfully), and when I chowned everything to my account, I missed a few directories.  Filling in those blanks made it start working.
