>                 URL: https://issues.apache.org/jira/browse/HBASE-18242
>             Project: HBase
>          Issue Type: Bug
>    Affects Versions: 0.98.10, 1.3.0
>            Reporter: Bo Cui
>            Priority: Minor
>
> There are two ways to open region:
> 1, RS#openRegion:flush, compact, split, merge, scan, get, etc.
> 2, Client#openRegion: only scan, get
> Either way, all files under /hbase/data/default/TableName/RegionEncodeName/.tmp will be deleted when region is initialized
> For method 2, this should not happen: the client opening region can only read data; there is no possibility of compaction; flush; if RS is processing compact, and client removes the TMP file, the RS needs to be re executed.
