Subject [jira] [Commented] (DRILL-901) Reading VarBinary data in parquet throws an error
Date Wed, 04 Jun 2014 18:35:03 GMT

    [ https://issues.apache.org/jira/browse/DRILL-901?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14017978#comment-14017978

Jason Altekruse commented on DRILL-901:
---------------------------------------

Updated patch slightly to include another small change. Previously when the parquet reader
would be passed a list of columns to read, and none matched the columns in the file we would
reach an NPE. The setup method has been updated to throw an exception with a reasonable error
message in this case.

> When reading one of the VarBinary columns in the TPCH dataset, found an edge case where
the parquet reader did not finish properly after reading all of the data. This caused an error
as it tried to read a page beyond the last one in the column chunk.
