> Project: HBase
> Issue Type: Bug
> Components: master, regionserver
> Affects Versions: 0.94.0
> Reporter: Aditya Kishore
> Assignee: Aditya Kishore
> Fix For: 0.92.2, 0.94.1
>
> Attachments: HBASE-6158_94.patch, HBASE-6158_trunk.patch

>
> If a table is creates with either 'merges' or 'splits' as one of the Column
> Family name it can never be flushed to the disk even though the table
> creation (and data population) succeeds.
> The reason for this is that these two are used as temporary directory names
> inside the region folder or merge and splits respectively and hence conflicts
> with the directories created for CF with same name.
> A simple fix would be to uses ".merges' and ".splits" as the working folder
> (patch attached). This will also be consistent with other work folder names.
> An alternate fix would be to declare these words (and other similar) as
> reserve words and throw exception when they are used. However, I do find the
> alternate approach as unnecessarily restrictive.
