[曾伟展]

Hi, ALL

    I used PE to test HBase-1.1.2 ，and cause many regionserver died !

and i don't know why  binarySearch return < 1


private final int findStripeIndexByEndRow(byte[] endRow) {
  assert !isInvalid(endRow);
  if (isOpen(endRow)) return state.stripeEndRows.length;
  return Arrays.binarySearch(state.stripeEndRows, endRow, 
Bytes.BYTES_COMPARATOR);
}
