[jira] [Comment Edited] (HIVE-17261) Hive use deprecated
ParquetInputSplit constructor which blocked parquet dictionary filter
[ https://issues.apache.org/jira/browse/HIVE-17261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16155410#comment-16155410 ]

-------------------------------------------------------------
Thanks [~junjie] for the patch. Some comments left below:
In ParquetRecordReaderBase.java
# Please remove @ Depercated annotation since we are not using the deprecated constructor in L65
# In L103 - L107, two space indents.
# Please update the setFilter method since the return value is no more needed.
# The searchArg is passing to setFilter as a final variable. Then the converted filter property is not passed to Parquet reader?

> Hive use deprecated ParquetInputSplit in [https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/io/parquet/ParquetRecordReaderBase.java#L128]
> Please see interface definition in [https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ParquetInputSplit.java#L80]
> Old interface set rowgroupoffset values which will lead to skip dictionary filter in parquet.
