Subject Re: New hadoop 1.2 single node installation giving problems
Date Tue, 23 Jul 2013 16:57:56 GMT
Thanks Jitendra, Bejoy and Yexi,

I got past that.  And now the ls command says it can not access the
directory.  I am sure this is a permissions issue.  I am just wondering
which directory and I missing permissions on.

Any pointers?

And once again, thanks a lot

Regards
ashish
