Hi

I Downloaded Sqoop from http://sqoop.apache.org and untar the file.
Added env variable SQOOP_HOME pointing to the above exploded folder.
Finally added $SQOOP_HOME/bin in the PATH.
Still i am getting this error

[hduser@master bin]$ ./sqoop-help
Warning: $HADOOP_HOME is deprecated.

Exception in thread "main" java.lang.NoClassDefFoundError:

Hello Prabhjot,

Which tarball did you download? The source tarball (
sqoop-1.4.1-incubating-src.tar.gz<http://apache.tradebit.com/pub/sqoop/1.4.1-incubating/sqoop-1.4.1-incubating-src.tar.gz>)
doesn't include Sqoop jar file, so you get that error. Please download one
of the following:

 sqoop-1.4.1-incubating__hadoop-0.20.tar.gz
<http://apache.tradebit.com/pub/sqoop/1.4.1-incubating/sqoop-1.4.1-incubating__hadoop-0.20.tar.gz>
 sqoop-1.4.1-incubating__hadoop-0.23.tar.gz
<http://apache.tradebit.com/pub/sqoop/1.4.1-incubating/sqoop-1.4.1-incubating__hadoop-0.23.tar.gz>
 sqoop-1.4.1-incubating__hadoop-1.0.0.tar.gz
<http://apache.tradebit.com/pub/sqoop/1.4.1-incubating/sqoop-1.4.1-incubating__hadoop-1.0.0.tar.gz>

Thanks,
Cheolsoo
