Package org.apache.hadoop.ipc

Class ProtobufHelper

java.lang.Object
org.apache.hadoop.ipc.ProtobufHelper
@Private @Deprecated public class ProtobufHelper extends Object
Deprecated.
hadoop code MUST use ShadedProtobufHelper.
Helper methods for protobuf related RPC implementation. This is deprecated because it references protobuf 2.5 classes as well as the shaded ones -and so needs an unshaded protobuf-2.5 JAR on the classpath during execution. It MUST NOT be used internally; it is retained in case existing, external applications already use it.

      Parameters:
      key - string
      Returns:
      the ByteString for frequently used fixed and small set strings.

    • getFixedByteString

      public static org.apache.hadoop.thirdparty.protobuf.ByteString getFixedByteString(String key)

      Deprecated.
      Get the byte string of a non-null byte array. If the array is 0 bytes long, return a singleton to reduce object allocation.
      Parameters:
      bytes - bytes to convert.
      Returns:
