A RemoteProcedureException is an exception from another thread or process.

RemoteProcedureExceptions are sent to 'remote' peers to signal an abort in the face of failures. When serialized for transmission we encode using Protobufs to ensure version compatibility.

RemoteProcedureException exceptions contain a Throwable as its cause. This can be a "regular" exception generated locally or a ProxyThrowable that is a representation of the original exception created on original 'remote' source. These ProxyThrowables have their their stacks traces and messages overridden to reflect the original 'remote' exception.

构造器详细资料

RemoteProcedureException

public RemoteProcedureException(String source,
                        Throwable cause)

Create a new RemoteProcedureException that can be serialized. It is assumed that this came form a local source.

参数:

source -

cause -

方法详细资料

getSource

public String getSource()

unwrapRemoteException

public IOException unwrapRemoteException()

toString

public String toString()

覆盖:

toString 在类中 Throwable

serialize

public static byte[] serialize(String source,
               Throwable t)

Converts a RemoteProcedureException to an array of bytes.

参数:

source - the name of the external exception source

t - the "local" external exception (local)

返回:

protobuf serialized version of RemoteProcedureException

deserialize

public static RemoteProcedureException deserialize(byte[] bytes)
                                            throws com.google.protobuf.InvalidProtocolBufferException

Takes a series of bytes and tries to generate an RemoteProcedureException instance for it.

参数:

bytes -

返回:

the ForeignExcpetion instance

抛出:

com.google.protobuf.InvalidProtocolBufferException - if there was deserialization problem this is thrown.

convert

public org.apache.hadoop.hbase.protobuf.generated.ErrorHandlingProtos.ForeignExceptionMessage convert()

toProto

public static org.apache.hadoop.hbase.protobuf.generated.ErrorHandlingProtos.ForeignExceptionMessage toProto(String source,
                                                                                             Throwable t)

fromProto

public static RemoteProcedureException fromProto(org.apache.hadoop.hbase.protobuf.generated.ErrorHandlingProtos.ForeignExceptionMessage eem)
