[jira] [Commented] (ORC-162) Handle 0 byte files as empty ORC files

    [ https://issues.apache.org/jira/browse/ORC-162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16027479#comment-16027479 ]

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

Hi, [~owen.omalley].
I'm doing SPARK-20901 `Feature parity for ORC with Parquet`.
This ORC issue is related with SPARK-19809. For me, the latest ORC seems to handle this when I test in SPARK-19809.
Is this not resolved?

> Hive often creates empty files for empty buckets, which can introduce significant load on the HDFS cluster. Therefore, they made the Hive OrcOutputFormat and OrcInputFormat use 0 byte ORC files as a special case.
> We need to make the other readers treat them reasonably.
