It takes the entire file as input otherwise it wont be any different from the normal line/record-based input format.

It takes entire file as input. There is a method in the class isSplittable in this input format class which is set to false. This method determines if file can be split in multiple chunks.

Hadoop doesn't find the input file

I am trying to run Nutch 2.2.1 on a Haddop 2-node cluster. My hadoop cluster is running fine and I have successfully added the input and output directory on to HDFS. But when I run

$HADOOP_HOME/bin/hadoop jar /nutch/apache-nutch-2.2.1.job org.apache.nutch.crawl.Crawler urls -dir crawl -depth 3 -topN 5

I am getting something like:

INFO input.FileInputFormat: Total input paths to process : 0

Which, I understand, is meaning that Hadoop cannot locate the input files. The job ends for obvious reasons citing the null pointer exception.

Can someone help me out?

insert overwrite table finaltable select * from staging;

I am not getting this logic. How should I populate the staging table daily.
