• required bytes bigdecimal_msg = 1

Used in: ColumnFamilySchema, TableSchema

• required bytes first = 1

• required bytes second = 2

Optional Cell block Message. Included in client RequestHeader

Used in: RequestHeader, ResponseHeader

• optional uint32 length = 1

  Length of the following cell block. Could calculate it but convenient having it too hand.

* Column Family Schema Inspired by the rest ColumSchemaMessage

Used in: TableSchema

• required bytes name = 1

• repeated BytesBytesPair attributes = 2

• repeated NameStringPair configuration = 3

ColumnFamily Specific TimeRange

This is sent on connection setup after the connection preamble is sent.

• optional UserInformation user_info = 1

• optional string service_name = 2

• optional string cell_block_codec_class = 3

  Cell block codec we will use sending over optional cell blocks. Server throws exception if cannot deal. Null means no codec'ing going on so we are pb all the time (SLOW!!!)

• optional string cell_block_compressor_class = 4

  Compressor we will use if cell block is compressed. Server will throw exception if not supported. Class must implement hadoop's CompressionCodec Interface. Can't compress if no codec.

• optional VersionInfo version_info = 5

• required string name = 1

• required double double_msg = 1

(message has no fields)

At the RPC layer, this message is used to carry the server side exception to the RPC client.

Used in: ResponseHeader

• optional string exception_class_name = 1

  Class name of the exception thrown from the server

• optional string stack_trace = 2

  Exception stack trace from the server side

• optional string hostname = 3

  Optional hostname. Filled in for some exceptions such as region moved where exception gives clue on where the region may have moved.

• optional int32 port = 4

• optional bool do_not_retry = 5

  Set if we are NOT to retry on receipt of this exception

* Protocol buffer for favored nodes

• required string value = 2

• required bytes name = 1

• repeated NameStringPair configuration = 2

* Description of the distributed procedure to take

• required string signature = 1

  the unique signature of the procedure

• optional string instance = 2

  the procedure instance name

• optional int64 creation_time = 3

• repeated NameStringPair configuration = 4

Used to pass through the information necessary to continue a trace after an RPC is made. All we need is the traceid (so we know the overarching trace this message is a part of), and the id of the current span when this message was sent, so we know what span caused the new span we will create when this message is received.

Used in: RequestHeader

• optional int64 trace_id = 1

• optional int32 replica_id = 7

* Description of the region server info

• optional int32 infoPort = 1

• optional VersionInfo version_info = 2

* Container protocol buffer to specify a region. You can specify region by region name, or the hash of the region name, which is known as encoded region name.

• required RegionSpecifier.RegionSpecifierType type = 1

• required bytes value = 2

Used in: RegionSpecifier

• REGION_NAME = 1

  <tablename>,<startkey>,<regionId>.<encodedName>

• ENCODED_REGION_NAME = 2

  hash of <tablename>,<startkey>,<regionId>

Header sent making a request.

• optional string method_name = 3

• optional bool request_param = 4

  If true, then a pb Message param follows.

• optional CellBlockMeta cell_block_meta = 5

  If present, then an encoded data block follows.

• optional uint32 priority = 6

  0 is NORMAL priority. 200 is HIGH. If no priority, treat it as NORMAL. See HConstants.

• optional uint32 timeout = 7

• optional uint32 call_id = 1

• optional ExceptionResponse exception = 2

  If present, then request threw an exception and no response message (else we presume one)
