-------------------------------------

             Summary:  Upgrade Apache ORC to 1.5.1
                 Key: SPARK-24576
                 URL: https://issues.apache.org/jira/browse/SPARK-24576
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.4.0
            Reporter: Dongjoon Hyun


This issue aims to upgrade Apache ORC library from 1.4.4 to 1.5.1 in order to bring the following benefits into Apache Spark.
 * ORC-91 Support for variable length blocks in HDFS (The current space wasted in ORC to padding is known to be 5%.)
 * ORC-344 Support for using Decimal64ColumnVector

In addition to that, Apache Hive 3.1.0 will use ORC 1.5.1 (HIVE-19669). This will improve the compatibility between Apache Spark and Apache Hive.
