Subject [jira] [Updated] (SQOOP-3149) Sqoop incremental import - NULL column updates are not pulled into HBase table
Date Fri, 10 Mar 2017 08:44:04 GMT

     [ https://issues.apache.org/jira/browse/SQOOP-3149?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jilani Shaik updated SQOOP-3149:
--------------------------------
    Description: 
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.

  was:

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 should provide a support to delete those columns
which are NULL in source, As HBase will not store the NULL columns.
