The ArcTool package is parsing and processing arc files. I uploaded the Jar with sources on /cs/phd/ouaknine/process_arc.jar
Job run example: bin/hadoop jar ~/process_arc.jar ArcProcessing -libjars=/cs/phd/ouaknine/PhD/lawa/arcTools/heritrix-1.14.4.jar,/cs/phd/ouaknine/PhD/lawa/arcTools/fastutil-6.1.0.jar keren1GB/ /user/ouaknine/output/sum4
The reader of the arc file is based on Heritrix parser.
Done:
- Implemented new InputFormat (ArcInputFormat, ArcRecordReader, ArcRecord)
- Implemented processing class
- Implemented layer between HDFS and heritrix's parser
- Tests on 1GB, waiting for main cluster to process more.
To be checked:
- Corrupted files exist in our data sets. Even though rare (less than 2%), these files prevents to complete the job, thus removed. I am checking issue with Internet Memory.
