David Severski commented on DRILL-7518: --------------------------------------- Can confirm that my previously failing parquet file can now be queried with the apache/drill:master docker image (built after this was merged). Thanks to everyone for the speedy diagnosis and fix! > Parquet INT64 Nullable Type Support > ----------------------------------- > > Key: DRILL-7518 > URL: https://issues.apache.org/jira/browse/DRILL-7518 > Project: Apache Drill > Issue Type: Bug > Affects Versions: 1.17.0 > Environment: Tested on the apache/drill:1.17.0 docker image. > Reporter: David Severski > Assignee: Arina Ielchiieva > Priority: Major > Labels: ready-to-commit > Fix For: 1.18.0 > > > Querying a parquet file with fields of type INT64 generates an immediate > error in the complex parquet reader with an error of "Unsupported nullable > converted type INT_64 for primitive type INT64". Attempts to work around this > via explicit CAST() and CONVERT_FROM() are unsuccessful. The suggestion from > drill-users is that an implementation needs to be made at > https://github.com/apache/drill/blob/9993fa3547b029db5fe33a2210fa6f07e8ac1990/exec/java-exec/src/main/java/org/apache/drill/exec/store/parquet/columnreaders/ColumnReaderFactory.java#L303. > > If related, a similar INT32 type field in the same file exhibits this > problem, but can be worked around via an explicit CAST() to INT. > > At this time, I do not have a sanitized parquet file to submit as a reference > example. :( > > Reference thread on drill-users list: > http://mail-archives.apache.org/mod_mbox/drill-user/202001.mbox/%3ccajguoa53ldkxqsh1fsvtj+dk5421eg4aw4paim++8bferxd...@mail.gmail.com%3e -- This message was sent by Atlassian Jira (v8.3.4#803005)
