-/**
- * <code>RCFile</code>s, short of Record Columnar File, are flat files
- * consisting of binary key/value pairs, which shares much similarity with
- * <code>SequenceFile</code>.
- *
- * RCFile stores columns of a table in a record columnar way. It first
- * partitions rows horizontally into row splits. and then it vertically
- * partitions each row split in a columnar way. RCFile first stores the meta
- * data of a row split, as the key part of a record, and all the data of a row
- * split as the value part. When writing, RCFile.Writer first holds records'
- * value bytes in memory, and determines a row split if the raw bytes size of
- * buffered records overflow a given parameter<tt>Writer.columnsBufferSize</tt>,
- * which can be set like: <code>conf.setInt(COLUMNS_BUFFER_SIZE_CONF_STR,
- 4 * 1024 * 1024)</code> .
- * <p>
- * <code>RCFile</code> provides {@link Writer}, {@link Reader} and classes for
- * writing, reading respectively.

- * RCFile compresses values in a more fine-grained manner then record level
- * compression. However, It currently does not support compress the key part
- * yet. The actual compression algorithm used to compress key and/or values can
- * be specified by using the appropriate {@link CompressionCodec}.

- * -- an optional sync hash, information about the size of the row group, and

- * -- is equivalent to column-buffer-length if the RCFile is not compressed.
- *
- * column-buffer-uncompressed-length ::= VInt

- * -- The length in bytes of the current column key buffer
- *
- * column-key-buffer-length ::= VInt
- *
- * -- The column-key-buffer contains a sequence of serialized VInt values
- * -- corresponding to the byte lengths of the serialized column fields
- * -- in the corresponding rowgroup-column-buffer. For example, consider
- * -- an integer column that contains the consecutive values 1, 2, 3, 44.
- * -- The RCFile format stores these values as strings in the column buffer,
- * -- e.g. "12344". The length of each column field is recorded in
- * -- the column-key-buffer as a sequence of VInts: 1,1,1,2. However,
- * -- if the same length occurs repeatedly, then we replace repeated
- * -- run lengths with the complement (i.e. negative) of the number of
- * -- repetitions, so 1,1,1,2 becomes 1,~2,2.
- *
- * column-key-buffer ::= Byte[column-key-buffer-length]
- *
- * rowgroup-column-buffers ::= <rowgroup-value-buffer>+
- *
- * -- RCFile stores all column data as strings regardless of the
- * -- underlying column type. The strings are neither length-prefixed or
- * -- null-terminated, and decoding them into individual fields requires
- * -- the use of the run-length information contained in the corresponding
- * -- column-key-buffer.
- *
- * rowgroup-column-buffer ::= Byte[column-buffer-length]
- *
- * Byte ::= An eight-bit byte
- *
- * VInt ::= Variable length integer. The high-order bit of each byte
- * indicates whether more bytes remain to be read. The low-order seven
- * bits are appended as increasingly more significant bits in the
- * resulting integer value.
- *
- * Int ::= A four-byte integer in big-endian format.
- *
- * Text ::= VInt, Chars (Length prefixed UTF-8 characters)
