Subject [jira] [Commented] (HIVE-16352) Ability to skip or repair out of sync blocks with HIVE at runtime
Date Wed, 26 Aug 2020 14:41:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17185231#comment-17185231
] 

Navdeep Poonia commented on HIVE-16352:
---------------------------------------

I agree with [~belugabehr], this does not seem to be a very generic issue happening very often.
As an alternative, avro repair util can be used for one time data fix and investigate the
cause for avro block sync.

> 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.
