TestDictionary#testZeroValues demonstrates the problem, where a page of all null values is decoded using the DicitonaryValuesReader. Because there are no non-null values, the page values section is 0 byte, but the DictionaryValuesReader assumes there is at least one encoded value and attempts to read a bit width. The test passes a byte array to initFromPage with the offset equal to the array's length. The fix is to detect that there are no input bytes to read. To avoid adding validity checks to the read path, this sets the internal decoder to one that will throw an exception if any reads are attempted. Author: Ryan Blue <[email protected]> Closes apache#18 from rdblue/PARQUET-18-fix-nulls-with-dictionary and squashes the following commits: 0711766 [Ryan Blue] PARQUET-18: Fix all-null value pages with dict encoding.
