Subject [jira] [Created] (NUTCH-2250) CommonCrawlDumper : Invalid format + skipped parts
Date Thu, 14 Apr 2016 09:21:25 GMT
Thamme Gowda N created NUTCH-2250:

             Summary:  CommonCrawlDumper : Invalid format + skipped parts
                 Key: NUTCH-2250
             Project: Nutch
          Issue Type: Sub-task
          Components: commoncrawl
    Affects Versions: 1.12
         Environment: Linux x64
Java 7
Nutch 1.12
            Reporter: Thamme Gowda N

The following issues are found with CommonCrawlDumper;
1. Documents get duplicated in dump files
How to reproduce 
bin/nutch commoncrawldump  -segment .../segments -outputDir testdump -SimpleDateFormat -epochFilename
-jsonArray -reverseKey

The first ever written will contain 1 document.
second file includes two documents
third file includes first three documents and this grows linearly.

2.If a segment has many parts (part-00000, part-00001,...) only the first part (part-00000
) is being dumped

How to reproduce ?
Create segment with two parts (part-00000 and part-00001)
