Hi, I tried running sqoop without the environment variable. But unfortunately it doesn't solve the problem. The classes cannot be found. So I am very sure, that I need to set a classpath somewhere. But I don't know where.
I am working with version: Hadoop 0.20.203.0 2011/12/21 Kate Ting <k...@cloudera.com> > Hi Otto - since you don't need to set SQOOP_HOME, can you go ahead and > unset that environment variable and then try running sqoop? > > Also, which Hadoop version are you on? > > Regards, Kate > > On Tue, Dec 20, 2011 at 10:26 AM, Otto Rossbach > <otto.rossb...@googlemail.com> wrote: > > Hi, > > I do have some trouble setting up Sqoop.
