> Reading to ByteBuffer is broken in ParquetFooterInputFromCache

> The ParquetFooterInputFromCache.read(ByteBuffer bb) calls the readInternal
> method with the result parameter passed as 'len'. The value of the result
> parameter will always be -1 at this point, and because of this, the
> readInternal method won't read anything.
> {noformat}
> public int read(ByteBuffer bb) throws IOException {
> // Simple implementation for now - currently Parquet uses heap buffers.
> int result = -1;
> if (bb.hasArray()) {
> result = readInternal(bb.array(), bb.arrayOffset(), result); // The
> readInternal is called with result=-1
> if (result > 0) {
> bb.position(bb.position() + result);
> }
> } else {
> byte[] b = new byte[bb.remaining()];
> result = readInternal(b, 0, result); // The readInternal is called
> with result=-1
> bb.put(b, 0, result);
> }
> return result;
> }
> {noformat}
> {noformat}
> public int readInternal(byte[] b, int offset, int len) {
> if (position >= length) return -1;
> int argPos = offset, argEnd = offset + len; // Here argEnd will be -1
> while (argPos < argEnd) { // This condition will never be
> true, since argEnd=-1
> if (bufferIx == cacheData.length) return (argPos - offset);
> ByteBuffer data = cacheData[bufferIx].getByteBufferDup();
> int toConsume = Math.min(argEnd - argPos, data.remaining() - bufferPos);
> data.position(data.position() + bufferPos);
> data.get(b, argPos, toConsume);
> if (data.remaining() == 0) {
> ++bufferIx;
> bufferPos = 0;

> bufferPos += toConsume;

> argPos += toConsume;

> return len;

> {noformat}
> The read(ByteBuffer bb) method wasn't called before, but in the 1.11.0
> Parquet version, there were some optimizations (PARQUET-1542), so this method
> is called now. Because of this bug, the TestMiniLlapCliDriver and
> TestMiniLlapLocalCliDriver q tests are failing with the new Parquet version.
