Subject [jira] [Commented] (DRILL-3975) Partition Planning rule causes query failure due to IndexOutOfBoundsException on HDFS
Date Sun, 25 Oct 2015 04:11:27 GMT

    [ https://issues.apache.org/jira/browse/DRILL-3975?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14972998#comment-14972998
] 

Mehant Baid commented on DRILL-3975:
------------------------------------

This particular bug was happening when ParquetPruneScanRule was hitting IOOB in the logic
you pointed out when there was no need to perform any splitting (since for auto partitioning
scheme we get the partitioning column value from the file and not from the location). 

However while debugging this I found that the "selectionRoot" contained the scheme and "file"
did not contain the scheme potentially causing IOOB you might be seeing. Stripping out the
scheme makes sense, we cannot check for -1 [Here|https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/planner/DFSPartitionLocation.java#L30]
as it would cause the partitioning columns to be incorrectly empty.

> In attempting to run the extended test suite provided by MapR, there are a large number
of queries that fail due to issues in the PruneScanRule and specifically the DFSPartitionLocation
constructor line 31. It is likely due to issues with the code that are related to running
on HDFS where this code path has apparently not been tested.
