Field Detail
- PB_MAGIC
```
public static final byte[] PB_MAGIC
```
  Magic we put ahead of a serialized protobuf message. For example, all znode content is protobuf messages with the below magic for preamble.

Method Detail

prependPBMagic
```
public static byte[] prependPBMagic(byte[] bytes)
```
Prepend the passed bytes with four bytes of magic, PB_MAGIC, to flag what follows as a protobuf in hbase. Prepend these bytes to all content written to znodes, etc.

Parameters:
bytes - Bytes to decorate

Returns:
The passed bytes with magic prepended (Creates a new byte array that is bytes.length plus PB_MAGIC.length.

isPBMagicPrefix
```
public static boolean isPBMagicPrefix(byte[] bytes)
```
Parameters:
bytes - Bytes to check.
