Subject [jira] [Commented] (PARQUET-1482) [C++] Unable to read data from parquet file generated with parquetjs
Date Thu, 14 Mar 2019 22:40:00 GMT

    [ https://issues.apache.org/jira/browse/PARQUET-1482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16793129#comment-16793129

Rylan Dmello commented on PARQUET-1482:
---------------------------------------

Hi [~terag], I haven't looked at implementing these changes with the low-level API yet. I
see that "column_reader.cc" has a similar TypedRecordReader method as "record_reader.cc",
and that there's a similar conditional statement there that excludes DATA_PAGE_V2 pages.

I'm not super familiar with the low-level API, but I think a similar set of changes might
work for fixing this issue with the low-level API too. If you already have code that fixes
this, I'd recommend sending in a pull request for this. Otherwise I can take a closer look
at porting this fix to the low-level API tomorrow.
