> Redundant FSTableDescriptor update
> ----------------------------------
>
> Key: HBASE-7596
> URL: https://issues.apache.org/jira/browse/HBASE-7596
> Project: HBase
> Issue Type: Bug
> Components: master
> Affects Versions: 0.96.0, 0.94.4
> Reporter: Matteo Bertozzi
> Assignee: Matteo Bertozzi
> Priority: Trivial
> Attachments: HBASE-7596-v0.patch
>
>
> The TableAddFamilyHandler and TableDeleteFamilyHandler code looks like
> {code}
> // Update table descriptor in HDFS
> HTableDescriptor htd = this.masterServices.getMasterFileSystem()
> .addColumn(tableName, familyDesc);
> // Update in-memory descriptor cache
> this.masterServices.getTableDescriptors().add(htd);
> {code}
> while the ModifyTableHandler code is just
> {code}
> // Update descriptor
> this.masterServices.getTableDescriptors().add(this.htd);
> {code}
> The MasterFileSystem code looks like
> {code}
> HTableDescriptor htd = this.services.getTableDescriptors().get(tableName);
> // ...add/remove columns to the descriptor...
> this.services.getTableDescriptors().add(htd);
> {code}
> so, the service.getTableDescriptors().add() is called two times for the
> add/delete family handler. (and the table descriptor rewritten twice
> FSTableDescriptors.updateHTableDescriptor())
