[jira] [Commented] (HIVE-16352) Ability to skip or repair out of sync blocks with HIVE at runtime

["Zoltan Haindrich (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-16352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17263987#comment-17263987 ] 

Zoltan Haindrich commented on HIVE-16352:
-----------------------------------------

Is it really not avoidable to write things correctly
Are these incorrect files created when the writer is being shut down incorrectly  - or hive is possibly reading an incomplete file?
Although I think the best would be to have a writer which could give better consistency guarantees - I'm not against this change: because it's small and is off by default.
Any strong opinion against merging it?

> When a file is corrupted it raises the error java.io.IOException: Invalid sync! with hive.
>  Can we have some functionality to skip or repair such blocks at runtime to make avro more error resilient in case of data corruption.
