             Summary: Hive use index for queries will lose some data if the Query file is
compressed.
                 Key: HIVE-12877
                 URL: https://issues.apache.org/jira/browse/HIVE-12877
             Project: Hive
          Issue Type: Bug
          Components: Indexing
    Affects Versions: 1.2.1
         Environment: This problem exists in all Hive versions.no matter what platform
            Reporter: yangfang


Hive created the index using the extracted file length when the file is  the compressed,
but when to divide the data into pieces in MapReduce,Hive use the file length to compare with
the extracted file length,if
If it found that these two lengths are not matched, It filters out the file.So the query will
lose some data
