[jira] [Created] (DRILL-5838) Fix MaprDB filter pushdown for the case of nested field (reg. of DRILL-4264)

Volodymyr Vysotskyi created DRILL-5838:
------------------------------------------

             Summary: Fix MaprDB filter pushdown for the case of nested field (reg. of DRILL-4264)
                 Key: DRILL-5838
                 URL: https://issues.apache.org/jira/browse/DRILL-5838
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - MapRDB
    Affects Versions: 1.11.0
            Reporter: Volodymyr Vysotskyi
            Assignee: Volodymyr Vysotskyi


After the changes in DRILL-4264, filter for MaprDB tables operate only with root field name, but {{MaprDBJsonRecordReader}} expects to use condition with full field path. In MaprDB classes compares the results of calling {{org.ojai.FieldPath.asPathString()}} method for the fields from project list and from filter list. 
So current code works only for cases when compares root fields, but not nested.
