Examples of CumulativeCappedExponentialBackoff

com.cloudera.util.CumulativeCappedExponentialBackoff
This provides a simple reusable exponential backoff state object. Note that this only does calculations and tracks the backoff state but doesn't actually do backoffs (e.g. do blocking sleeps)! Later this could be pluggable with other backoff policies (maybe adaptive?) This policy has a max backoff per attempt and also a cumulative maximum failure time. After the cumulative time has expired isfailed will return true

    long initMs = FlumeConfiguration.get().getInsistentOpenInitBackoff();
    long cumulativeMaxMs = FlumeConfiguration.get()
        .getFailoverMaxCumulativeBackoff();
    long maxMs = FlumeConfiguration.get().getFailoverMaxSingleBackoff();
    BackoffPolicy backoff1 = new CumulativeCappedExponentialBackoff(initMs,
        maxMs, cumulativeMaxMs);
    BackoffPolicy backoff2 = new CumulativeCappedExponentialBackoff(initMs,
        maxMs, cumulativeMaxMs);
