@InterfaceAudience.Private
public class RpcRetryingCaller<T>
extends Object

Runs an rpc'ing RetryingCallable. 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 Summary

RpcRetryingCaller(org.apache.hadoop.conf.Configuration conf)

Method Summary

T	callWithoutRetries(RetryingCallable<T> callable) Call the server once only.
T	callWithRetries(RetryingCallable<T> callable)
T	callWithRetries(RetryingCallable<T> callable, int callTimeout) Retries if invocation fails.

Method Detail

callWithRetries

public T callWithRetries(RetryingCallable<T> callable)
                  throws IOException,
                         RuntimeException

Throws:

IOException

RuntimeException

callWithRetries

public T callWithRetries(RetryingCallable<T> callable,
                         int callTimeout)
                  throws IOException,
                         RuntimeException

Retries if invocation fails.

Parameters:

callTimeout - Timeout for this call

callable - The RetryingCallable to run.

Returns:

an object of type T

Throws:

IOException - if a remote or network exception occurs

RuntimeException - other unspecified error

callWithoutRetries

public T callWithoutRetries(RetryingCallable<T> callable)
                     throws IOException,
                            RuntimeException

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

Returns:

an object of type T

Throws:

IOException - if a remote or network exception occurs

RuntimeException - other unspecified error
