----------------------------------
Summary: Truncate table with preserve after split may cause
truncate fail
Key: HBASE-17319
URL: https://issues.apache.org/jira/browse/HBASE-17319
Project: HBase
Issue Type: Bug
Components: Admin
Affects Versions: 1.2.4, 1.1.7
Reporter: Allan Yang
Assignee: Allan Yang
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.
