Subject Re: where is IndexHDFS.java
Date Tue, 05 May 2015 16:01:24 GMT
Hello Mahmood,

I'm not aware of any Apache project with a class named IndexHDFS.  I just
did a scan over my local checkouts of the code for many of the Apache
projects, and I didn't find anything.

The fact that IndexHDFS is not prefixed with a package name in the stack
trace tells me that this is unlikely to be a class from any Apache
project.  Apache projects will put their classes into packages, usually
some form of org.apache...  Instead, this is likely to be application code
that you ran using "hadoop jar", coming from either your own project or
some kind of third-party tool that you're using.
