> HADOOP-16398 added exporter for hadoop metrics to prometheus. But some of
> metrics can't be exported validly. For example like these metrics,
> 1. -queue metrics for ResourceManager-
> {code:java}
> queue_metrics_max_capacity{queue="root.queue1",context="yarn",hostname="rm_host1"}
> 1
> // queue2's metric can't be exported
> queue_metrics_max_capacity{queue="root.queue2",context="yarn",hostname="rm_host1"}
> 2
> {code}
> -It always exported only one queue's metric because
> PrometheusMetricsSink$metricLines only cache one metric if theses metrics
> have the same name no matter these metrics has different metric tags.-
>
> 2. -rpc metrics for Namenode-
> -Namenode may have rpc metrics with multi port like service-rpc. But because
> the same reason as Issue 1, it wiil lost some rpc metrics if we use
> PrometheusSink.-
> {code:java}
> rpc_rpc_queue_time300s90th_percentile_latency{port="9000",servername="ClientNamenodeProtocol",context="rpc",hostname="nnhost"}
> 0
> // rpc port=9005 metric can't be exported
> rpc_rpc_queue_time300s90th_percentile_latency{port="9005",servername="ClientNamenodeProtocol",context="rpc",hostname="nnhost"}
> 0
> {code}
> 3. TopMetrics for Namenode
> org.apache.hadoop.hdfs.server.namenode.top.metrics.TopMetrics is a special
> metric. And I think It is essentially a Summary metric type. TopMetrics
> record name will according to different user and op , which means that these
> metric will always exist in PrometheusMetricsSink$metricLines and it may
> cause the risk of its memory leak. We e need to treat it special.
> {code:java}
> // invaild topmetric export
> # TYPE
> nn_top_user_op_counts_window_ms_1500000_op_safemode_get_user_hadoop_client_ip_test_com_count

> 10
> // it should be
> # TYPE nn_top_user_op_counts_window_ms_1500000_count counter
> nn_top_user_op_counts_window_ms_1500000_count{context="dfs",hostname="nn_host",op="safemode_get",user="hadoop/[email protected]"}
