lelence opened a new issue #2376: 关于使用中的几个问题
URL: https://github.com/apache/incubator-skywalking/issues/2376
 
 
   你好， 我再使用 `6.0.0-GA` 版本, 下面是我的docker-compose.yml, 我想搭建一个多 `OAP`的 APM 环境,  发现了几个问题<br/>
   
   
   1. 两个`OAP`的时候, 总会有一个报错的, 是不是 这里不可以对 `OAP` 做 高可用的配置
   
   > org.elasticsearch.client.ResponseException: method [PUT], host [http://elasticsearch:9200], URI [/all_heatmap_hour?master_timeout=30s&timeout=30s], status line [HTTP/1.1 400 Bad Request]
   {"error":{"root_cause":[{"type":"resource_already_exists_exception","reason":"index [all_heatmap_hour/4n3lxsqIQUGiXOeJixPC2A] already exists","index_uuid":"4n3lxsqIQUGiXOeJixPC2A","index":"all_heatmap_hour"}],"type":"resource_already_exists_exception","reason":"index [all_heatmap_hour/4n3lxsqIQUGiXOeJixPC2A] already exists","index_uuid":"4n3lxsqIQUGiXOeJixPC2A","index":"all_heatmap_hour"},"status":400}
   
   2. 如果有一个 `OAP` 宕机之后, `UI` 的 zuul + ribbon 总是 不能 及时响应, 总会出现, 我也试着修改了相关参数, 还是会出现下面的情况
   
   > com.netflix.zuul.exception.ZuulException: Forwarding error
   	at org.springframework.cloud.netflix.zuul.filters.route.RibbonRoutingFilter.handleException(RibbonRoutingFilter.java:189)
