Class AsyncRpcRetryingCaller<T>

java.lang.Object

org.apache.hadoop.hbase.client.AsyncRpcRetryingCaller<T>

Type Parameters:

T - Type of Response

public class AsyncRpcRetryingCaller<T>
extends java.lang.Object

Runs an rpc'ing AsyncRetryingCallable. Sets into rpc client threadlocal outstanding timeouts as so we don't persist too much. Dynamic rather than static so can set the generic appropriately.

Constructor Detail

AsyncRpcRetryingCaller

public AsyncRpcRetryingCaller(long pause,
                      int retries)

Constructor

Parameters:

pause - before retry

retries - max amount of retries

Method Detail

callWithRetries

public void callWithRetries(AsyncRetryingCallable<T> callable,
                   ResponseHandler<T> handler)

Retries if invocation fails.

Parameters:

callable - to run

handler - to handle response

callWithRetries

public void callWithRetries(AsyncRetryingCallable<T> callable,
                   int callTimeout,
                   ResponseHandler<T> handler)

Retries if invocation fails.

Parameters:

callTimeout - Timeout for this call

handler - to handle response

callable - The AsyncRetryingCallable to run.

callWithoutRetries

public void callWithoutRetries(AsyncRetryingCallable<T> callable,
                      int callTimeout,
                      ResponseHandler<T> handler)

Call the server once only. AsyncRetryingCallable has a strange shape so we can do retries. Use this invocation if you want to do a single call only (A call to AsyncRetryingCallable.call(ResponseHandler) will not likely succeed).

Parameters:

callable - to call

callTimeout - to timeout call

handler - for response
