Subject [jira] [Commented] (DRILL-1701) Drill chooses the optimized reader that only supports flat data, rather than the one that supports complex in the case where there is a simple non-repeated map type

    [ https://issues.apache.org/jira/browse/DRILL-1701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14211515#comment-14211515

Jason Altekruse commented on DRILL-1701:
----------------------------------------

The initial patch posted did not address the real issue with the file being read. The file
was a completely flat schema, however when I checked the file with the parquet-tools I mis
interpreted the output because the file actually contained json structures within a var-binary
field, which I mistook as output to represent a map in the file. The real issue was a bug
reading nullable dictionary encoded data, which is posted with the 'b' version of the patch.
