Subject [jira] [Commented] (HIVE-11209) Clean up dependencies in HiveDecimalWritable
Date Tue, 21 Jul 2015 23:35:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11209?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14636017#comment-14636017

Prasanth Jayachandran commented on HIVE-11209:
----------------------------------------------

Vint object is no longer reusable with this patch. Vint allocation in inner loop will hit
performance right?

> Currently HiveDecimalWritable depends on:
> * org.apache.hadoop.hive.serde2.ByteStream
> * org.apache.hadoop.hive.serde2.lazybinary.LazyBinaryUtils
> * org.apache.hadoop.hive.serde2.typeinfo.HiveDecimalUtils
> since we need HiveDecimalWritable for the decimal VectorizedColumnBatch, breaking these
dependencies will improve things.
