解决方法 

Avro Sink
This sink forms one half of Flume’s tiered collection support. Flume events sent to this sink are turned into Avro events and sent to the configured hostname / port pair. The events are taken from the configured Channel in batches of the configured batch size. Required properties are in bold.

Property Name    Default    Description
channel    –     
type    –    The component type name, needs to be avro.
hostname    –    The hostname or IP address to bind to.
port    –    The port # to listen on.
batch-size    100    number of event to batch together for send.
connect-timeout    20000    Amount of time (ms) to allow for the first (handshake) request.
request-timeout    20000    Amount of time (ms) to allow for requests after the first.
reset-connection-interval    none    Amount of time (s) before the connection to the next hop is reset. This will force the Avro Sink to reconnect to the next hop. This will allow the sink to connect to hosts behind a hardware load-balancer when news hosts are added without having to restart the agent.
