    Description

      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:

      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

      The truncateTableProcedue will retry forever and never get success.
      A attached unit test shows everything.
