Subject [jira] [Commented] (DRILL-4464) Apache Drill cannot read parquet generated outside Drill: Reading past RLE/BitPacking stream
Date Wed, 08 Jun 2016 16:44:21 GMT

    [ https://issues.apache.org/jira/browse/DRILL-4464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15320903#comment-15320903
] 

John Omernik commented on DRILL-4464:
-------------------------------------

Note: Like in the case of my data, when we set store.parquet.use_new_reader to true, the data
in the sample file on this JIRA no longer throws an error.

> When I generate file using MapReduce and parquet 1.8.1 (or 1.8.1-drill-r0), which contains
REQUIRED INT64 field, I'm not able to read this column in drill, but I'm able to read full
content using parquet-tools cat/dump. This doesn't happened every time, it is input data dependant
(so probably different encoding is chosen by parquet for given column?).

> When I change fields in schema to optional and regenerate file, drill will start working.
Same when I generate file using CTAS (which have all columns optional as well).
