Hi,
I was trying to run the DumpWikipediaToPlainText job of the Cloud9
library for Hadoop
(http://www.umiacs.umd.edu/~jimmylin/Cloud9/docs/content/wikipedia.html). It
requires two extra libraries which are .jar files -
bliki-core-3.0.16.jar and commons-lang-2.6.jar (available from
http://code.google.com/p/scalaris/). On running:
"bin/hadoop jar cloud9-1.2.4.jar
edu.umd.cloud9.collection.wikipedia.DumpWikipediaToPlainText -libjars
bliki-core-3.0.16.jar,commons-lang-2.6.jar -input /wc_input/ -output
/wikidata_text",
I get the following error:
11/09/16 23:55:31 INFO mapred.JobClient: Cleaning up the staging area

Could someone please help me solve this problem? I am using the cloudera
distribution of Hadoop-0.20.2.
Thanks,
