A call to this constructor should be followed by call to configure().public void close()
throws FlumeException
RpcClientImmediately closes the client so that it may no longer be used.
Note: This method MUST be called by applications when they are done using the RPC client in order to clean up resources.
Multi-threaded applications may want to gracefully stop making
RPC calls before calling close(). Otherwise, they risk getting
EventDeliveryException thrown from their in-flight calls when the
underlying connection is disabled.
close in interface RpcClientclose in class AbstractRpcClientFlumeExceptionpublic void append(Event event) throws EventDeliveryException
RpcClientSend a single Event to the associated Flume source.
This method blocks until the RPC returns or until the request times out.
Note: If this method throws an
EventDeliveryException, there is no way to recover and the
application must invoke RpcClient.close() on this object to clean up system
resources.
append in interface RpcClientappend in class AbstractRpcClientEventDeliveryException - when an error prevents event delivery.public void appendBatch(List<Event> events) throws EventDeliveryException
RpcClientSend a list of events to the associated Flume source.
This method blocks until the RPC returns or until the request times out.
It is strongly recommended that the number of events in the List be no
more than RpcClient.getBatchSize(). If it is more, multiple RPC calls will
be required, and the likelihood of duplicate Events being stored will
increase.
Note: If this method throws an
EventDeliveryException, there is no way to recover and the
application must invoke RpcClient.close() on this object to clean up system
resources.

RpcClientReturns true if this object appears to be in a usable state, and
it returns false if this object is permanently disabled.
If this method returns false, an application must call
RpcClient.close() on this object to clean up system resources.
isActive in interface RpcClientisActive in class AbstractRpcClientpublic void configure(Properties properties) throws FlumeException
Configure the actual client using the properties. properties should have at least 2 params:
hosts = alias_for_host
alias_for_host = hostname:port.
Only the first host is added, rest are discarded.Optionally it can also have a
batch-size = batchSize

method, or if the client was already configured once.Copyright © 2009-2022 Apache Software Foundation. All Rights Reserved.
