1.架构说明
开始是使用 1follow+1observe+3be
后续由于感觉服务器fe负载压力大 将fe修改为3个follower节点。使用nginx作负载。
2.通讯问题，偶尔出现下面的错误
(1105, "errCode = 2, detailMessage = (172.15.2.26)[THRIFT_RPC_ERROR]Couldn't open transport for 172.15.2.25:9020 (socket open() error: Connection reset by peer)")
(1105, 'errCode = 2, detailMessage = (172.15.2.28)[INTERNAL_ERROR]ReportExecStatus() to TNetworkAddress(hostname=172.15.2.25, port=9020) failed: No more data to read.')
(2013, 'Lost connection to server during query')
3.gc频繁，young gc 非常频繁（几秒钟一次）使用一段时间后，full gc也很频繁，然后服务宕机。服务出现卡顿时 发现执行 show frontends 需要30s
