Description

protected HRegion openHRegion(final CancelableProgressable reporter)
throws IOException {
  try {
    ......
  } catch(Throwable t) {
    // By coprocessor path wrong region will open failed,
    // MetricsRegionWrapperImpl is already init and not close,
    // add region close when open failed
    this.close(); // This may throw IOException too.
    throw t;
  }
  return this;
}

this.close() may throw IOException too. The original exception will not be recorded.
