类 RetryCounter

java.lang.Object

org.apache.hadoop.hbase.util.RetryCounter

@InterfaceAudience.Private
public class RetryCounter
extends Object

Operation retry accounting. Use to calculate wait period, getBackoffTimeAndIncrementAttempts()}, or for performing wait, sleepUntilNextRetry(), in accordance with a RetryCounter.RetryConfig, initial settings, and a Retry Policy, (See org.apache.hadoop.io.retry.RetryPolicy). Like guava-retrying.
