----------------------------------

             Summary: simplify the logic of getRegionInfo in TestFlushFromClient to reduce redundancy code
                 Key: HBASE-24821
                 URL: https://issues.apache.org/jira/browse/HBASE-24821
             Project: HBase
          Issue Type: Improvement
          Components: test
            Reporter: Zheng Wang
            Assignee: Zheng Wang


Current logic:
{code:java}
  private List<HRegion> getRegionInfo() {
    return TEST_UTIL.getHBaseCluster().getLiveRegionServerThreads().stream()
      .map(JVMClusterUtil.RegionServerThread::getRegionServer)
      .flatMap(r -> r.getRegions().stream())
      .filter(r -> r.getTableDescriptor().getTableName().equals(tableName))
      .collect(Collectors.toList());
  }
{code}
The MiniHBaseCluster has similar method to do same thing.
 So it could just directly call:
{code:java}
  private List<HRegion> getRegionInfo() {
    return TEST_UTIL.getHBaseCluster().getRegions(tableName);
  }
{code}
