> Key: HBASE-17319
> URL: https://issues.apache.org/jira/browse/HBASE-17319
> Project: HBase
> Issue Type: Bug
> Components: Admin
> Affects Versions: 1.1.7, 1.2.4
> Reporter: Allan Yang

> Fix For: 1.4.0
>
> Attachments: HBASE-17319-branch-1.patch, HBASE-17319.patch
>
>
> In truncateTableProcedue , when getting tables regions from meta to recreate
> new regions, split parents are not excluded, so the new regions can end up
> with the same start key, and the same region dir:
> {noformat}
> 2016-12-14 20:15:22,231 WARN [RegionOpenAndInitThread-writetest-1]
> regionserver.HRegionFileSystem: Trying to create a region that already exists
> on disk:
> hdfs://hbasedev1/zhengyan-hbase11-func2/.tmp/data/default/writetest/9b2c8d1539cd92661703ceb8a4d518a1
> {noformat}
> The truncateTableProcedue will retry forever and never get success.
> A attached unit test shows everything.
