[jira] [Created] (HIVE-2658) add a option in hive to skip corrupted data entirely

add a option in hive to skip corrupted data entirely
----------------------------------------------------

                 Key: HIVE-2658
                 URL: https://issues.apache.org/jira/browse/HIVE-2658
             Project: Hive
          Issue Type: New Feature
            Reporter: Namit Jain
            Assignee: He Yongqiang


Add a new parameter:

hive.skip.corrupted.data

This is independent of the type of the underlying data.

The idea is as follows:

We have some corrupted data in our cluster right now.
We will run hive over all the corrupted partitions:

use bucketizedhiveinputformat
set hive.skip.corrupted.data=true

insert overwrite table <T> partition <P> 
select * from <T> where <P>

This way, <T>@<P> will be regenerated with all the data that can be read.

If HiveRecordReader gets a exception getting the next row, the mapper will behave as if no more data is present in the file.

Namit Jain resolved HIVE-2658.
------------------------------

    Resolution: Won't Fix

Not needed - it will be difficult to come up with a generic 
exception.
