Subject [jira] [Updated] (HBASE-11653) RegionObserver coprocessor cannot override KeyValue values in prePut()
Date Sat, 02 Aug 2014 01:05:38 GMT

     [ https://issues.apache.org/jira/browse/HBASE-11653?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gary Helmling updated HBASE-11653:
----------------------------------

    Priority: Minor  (was: Critical)

Since this only applies to {{HRegion.internalPut()}}, which is not triggered by normal client
actions (they instead go through {{HRegion.put(Put[])}} which calls {{batchMutate()}}, this
is only a minor issue.

>                 Key: HBASE-11653
>                 URL: https://issues.apache.org/jira/browse/HBASE-11653
>             Project: HBase
>          Issue Type: Bug
>          Components: Coprocessors
>    Affects Versions: 0.94.21
>            Reporter: Gary Helmling
>            Assignee: Gary Helmling
>            Priority: Minor
>
> Due to a bug in {{HRegion.internalPut()}}, any modifications that a {{RegionObserver}}
makes to a Put's family map in the {{prePut()}} hook are lost.
> This prevents coprocessors from modifying the values written by a {{Put}}.
