---------------------------------------
look for HIVE-14514 in OrcRecordUpdater
> OrcRecordUpdater should clone writerOptions when creating delete event writers
> ------------------------------------------------------------------------------

> Key: HIVE-14514
> URL: https://issues.apache.org/jira/browse/HIVE-14514
> Project: Hive
> Issue Type: Improvement
> Components: Transactions
> Affects Versions: 2.2.0
> Reporter: Saket Saurabh
> Assignee: Eugene Koifman
> Priority: Minor
>
> When split-update is enabled for ACID, OrcRecordUpdater creates two sets of
> writers: one for the insert deltas and one for the delete deltas. The
> deleteEventWriter is initialized with similar writerOptions as the normal
> writer, except that it has a different callback handler. Due to the lack of
> copy constructor/ clone() method in writerOptions, the same writerOptions
> object is mutated to specify a different callback for the delete case.
> Although, this is harmless for now, but it may become a source of confusion
> and possible error in future. The ideal way to fix this would be to create a
> clone() method for writerOptions- however this requires that the parent class
> of WriterOptions in the OrcFile.WriterOptions should implement Cloneable or
> provide a copy constructor.
