org.apache.hadoop.io.compress.lz4.Lz4Decompressor.decompress()
Fills specified buffer with uncompressed data. Returns actual number of bytes of uncompressed data. A return value of 0 indicates that {@link #needsInput()} should be called in order to determine if moreinput data is required. @param b Buffer for the compressed data @param off Start offset of the data @param len Size of the buffer @return The actual number of bytes of compressed data. @throws IOException
