Subject [jira] [Commented] (HBASE-8318) TableOutputFormat.TableRecordWriter should accept Increments
Date Fri, 12 Apr 2013 18:32:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8318?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13630448#comment-13630448

Jean-Daniel Cryans commented on HBASE-8318:
-------------------------------------------

Generally, using ICV in MR jobs is a bad idea because of speculative execution which is enabled
by default, and even if it's disabled your tasks can just fail and then they get restarted
somewhere else and you never know how many times you incremented some cells.

So, what's a valid use case for this jira?

> TableOutputFormat.TableRecordWriter can take Puts and Deletes but it should also accept
Increments.
