@prasanthj yeah, in general you should make a dev branch for the pull
request (eg. prasanthj:orc-373). Then you can do a force-push to the branch to
update the PR.
> Option to disable dictionary encoding
> --------------------------------------
>
> Key: ORC-373
> URL: https://issues.apache.org/jira/browse/ORC-373
> Project: ORC
> Issue Type: Bug
> Affects Versions: 1.5.2
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
> Priority: Major
>
> Currently dictionary check happens after creation of first row group entry.
> Even when row indexes are disabled, rows end up in red-black tree first
> before getting flushed during write stripe (into direct stream).
> If dictionary threshold is set to <= 0.0 disable dictionary, we should write
> directly to stream instead of RBTree. This is useful for hive streaming
> ingest where delta files explicitly disables dictionaries.
