Subject Create table threw NullPointerException
Date Fri, 15 Jul 2011 02:43:50 GMT
It happened in latest branch 0.90. but I can't reproduce it.

It seems using api getHRegionInfoOrNull is better or check the input parameter before call

  public static Writable getWritable(final byte [] bytes, final Writable w)
  throws IOException {
    return getWritable(bytes, 0, bytes.length, w);
return getWritable(bytes, 0, bytes.length, w);  // It seems input parameter bytes is null
