> The issue is reported by [~dsen]:
> Recently added Namenode metric "rpc.RetryCache/NameNodeRetryCache.CacheHit"
> can't be correctly processed by Ganglia because its name contains "/"
> Proposal: Namenode metric "rpc.RetryCache/NameNodeRetryCache.CacheHit" should
> be renamed to "rpc.RetryCache.NameNodeRetryCache.CacheHit"
> Here - org.apache.hadoop.ipc.metrics.RetryCacheMetrics#RetryCacheMetrics
> {code}
> RetryCacheMetrics(RetryCache retryCache) {
> name = "RetryCache/"+ retryCache.getCacheName();
> registry = new MetricsRegistry(name);
> if (LOG.isDebugEnabled()) {
> LOG.debug("Initialized "+ registry);
> }
