[jira] [Updated] (ORC-670) RecordReaderImpl.findColumns should respect orc.schema.evolution.case.sensitive

     [ https://issues.apache.org/jira/browse/ORC-670?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dongjoon Hyun updated ORC-670:
------------------------------
    Description: 
This is a performance regression from 1.5.x. Apache ORC 1.6 always behaves case-sensitively.

Without this, ORC 1.6.x cannot pass SPARK-32622 (case sensitivity in predicate pushdown) unit test case.

  was:
This is a performance regression from 1.5.x.

Without this, ORC 1.6.x cannot pass SPARK-32622 (case sensitivity in predicate pushdown) unit test case.
