Error in configuring object when converting intoTika using Behemoth and map reduce

I am running the command to convert behemoth corpus to tika using map reduce as given in this tutorial

I am getting following error on doing it:

I am not able to understand the exact problem.What could be the possible reasons?Do i need to add copy any jar from Behemoth/Tika to hadoop working directory?

Solution

  • I had the same problem. The procedure, as described on this page has helped me. After I run "mvn clean install", the tika job worked as described in the tutorial.
