-------------------------------------
Summary: Add cleanup call in Fetcher.java
Key: NUTCH-2911
URL: https://issues.apache.org/jira/browse/NUTCH-2911
Project: Nutch
Issue Type: Improvement
Components: fetcher
Reporter: Prakhar Chaube
Fetcher's inner class, FetcherRun overrides Hadoop Mapper's run().
Even though Nutch's FetcherRun doesn't need an explicit call the Mapper's
cleanup() (Which is a blank function), it would increase the readability and
completeness of the run Method to do so.
Ideally, every implementation of Mapper is supposed to do the following tasks:
1. Perform Setup
2. Call map on the data set
3. Perform cleanups.
Moreover, in case a custom Fetcher is written extending Fetcher.java cleanup
could get easily missed out.
