【详述】FE的Leader运行一段时间后，8030端口响应变慢。
如Flink 通过StreamLoad写入数据到SR出现超时。
Grafana 界面上的图表无法获取Leader的信息，集群的Tablet为N/A。
手动执行获取Leader的metrics(http://fe_leader_ip:8030/metrics)也响应慢。
Leader 的8030慢的时候，Follower的8030是正常的，手动执行http获取metris就能对比出来。
重启FE的Leader后，上述问题就解决了，但是过一段时间，Leader的8030又会变慢，目前都是通过重启FE的Leader来解决的。

This can happen when FE responds the request slowly , you should find the reason first.

FE的Leader发生慢的时候没有做Full GC
