Subject [jira] [Created] (BLUR-375) PrimeDoc moves during MR indexing overflow
Date Tue, 09 Sep 2014 14:52:28 GMT
Aaron McCurry created BLUR-375:
----------------------------------

             Summary: PrimeDoc moves during MR indexing overflow
                 Key: BLUR-375
                 URL: https://issues.apache.org/jira/browse/BLUR-375
             Project: Apache Blur
          Issue Type: Bug
          Components: Blur MapReduce
    Affects Versions: 0.2.4, 0.2.3
            Reporter: Aaron McCurry
            Priority: Blocker
             Fix For: 0.2.4


During MapReduce indexing, if the number of records in a row exceeds the memory limit and
the indexer has to overall to disk the first document added to that tmp index is the prime
doc.  However if that overflow index goes through several merges the primedoc may not be the
first document in the tmp index.  If this occurs it causes problems in the row queries once
the indexes are brought online in a blur table.
