Change subject: KUDU-1651: Check empty dict before decoder eval ...................................................................... KUDU-1651: Check empty dict before decoder eval A completely null dictionary-encoded column will yield an empty dictionary. When decoder-level evaluation is on, this will result in an error when creating the bitmap of matching codewords, as bitmaps must have a non-zero size. In this scenario, it is sufficient to not determine the set of matching codewords. The decoder should be completely skipped over given a null column, so the matching codeword set would not be used here. If the decoder is not skipped over and an attempt is made to read from the dictionary block, an error should be thrown.
