Description

In MetricsRegionServerWrapperImpl, walFileSize is calculated by provider.getLogFileSize() twice as follows, which is causing the wrong WAL size in RegionServer UI:

        walFileSize = (provider == null ? 0 : provider.getLogFileSize()) +
            (provider == null ? 0 : provider.getLogFileSize());
