Description

The method contains the following code:

        LOG.warn(FairSchedulerConfiguration.UPDATE_INTERVAL_MS
            + " is invalid, so using default value "
            + +FairSchedulerConfiguration.DEFAULT_UPDATE_INTERVAL_MS
            + " ms instead");

Note the beginning of the third line. One of those plusses should be deleted so that no one else spends cycles trying to understand why it even compiles.
