Subject [jira] [Commented] (HBASE-8626) RowMutations fail when Delete and Put on same columnFamily/column/row
Date Sun, 02 Jun 2013 22:34:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8626?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13672702#comment-13672702

Vinod commented on HBASE-8626:
------------------------------

Lars, the approach you suggest does not work for my use-case because of the race-condition
mentioned by Ted in his comment above at:
https://issues.apache.org/jira/browse/HBASE-8626?focusedCommentId=13669464&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13669464


Can we extend current RowMutations to support something like what Andrew stated in his previous
comment here:
https://issues.apache.org/jira/browse/HBASE-8626?focusedCommentId=13669152&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13669152

That would solve my use-case perfectly.

> When RowMutations have a Delete followed by Put to same column family or columns or rows,
only the Delete is happening while the Put is ignored so atomicity of RowMutations is broken
for such cases.
> Attached is a unit test where the following tests are failing:
> - testDeleteCFThenPutInSameCF: Delete a column family and then Put to same column family.
> - testDeleteColumnThenPutSameColumn: Delete a column and then Put to same column.
> - testDeleteRowThenPutSameRow: Delete a row and then Put to same row
