> Sqoop incremental import - NULL column updates are not pulled into HBase
> table
> -------------------------------------------------------------------------------
>
> Key: SQOOP-3149
> URL: https://issues.apache.org/jira/browse/SQOOP-3149
> Project: Sqoop
> Issue Type: Bug
> Components: connectors/generic, hbase-integration
> Affects Versions: 1.4.6
> Reporter: Jilani Shaik
> Attachments: hbase_delete_support_in_incremental_import
>
>
> Sqoop incremental import data from any database to HBase, if source table's
> column from a row is updated to NULL, then target HBase table still showing
> the previous value for that column.
> So if you do a scan on the table for that row, HBase shows the previous
> values of the column.
> Expected Result: Sqoop incremental import, If NULL columns are there in
> source, then HBase need not store that and if it already exists need to
> delete that column for a given row.
