Hej,
I am developing a project based on Nutch. It works great (in Eclipse) but
due to new requirements I have to change the library hadoop-0.12.2-core.jar
to the original source code.
I download succesfully that code in:
http://archive.apache.org/dist/hadoop/core/hadoop-0.12.2/hadoop-0.12.2.tar.gz.
After adding it to the project in Eclipse everything seems correct but the
execution shows:
Exception in thread "main" java.io.IOException: No FileSystem for scheme:
file
at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:157)
at org.apache.hadoop.fs.FileSystem.getNamed(FileSystem.java:119)
at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:91)
at org.apache.nutch.crawl.Crawl.main(Crawl.java:103)
Any idea?
Yes - when you worked with a pre-built jar it contained an embedded
hadoop-default.xml that defines the implementation of the "file://"
schema FileSystem. Now you probably forgot to put hadoop-default.xml on
your classpath. Go to Build Path and add this file to your classpath,
and all should be ok.
