elasticsearch启动时报错，却可以正常使用

Question

我的elasticsearch启动日志里出现了2个warn日志，大概是

All shards failed for phase: [query]
index=.kibana
"stacktrace": ["org.elasticsearch.action.search.SearchPhaseExecutionException: all shards failed"

和

All shards failed for phase: [query]
index=.kibana_task_manager
"stacktrace": ["org.elasticsearch.action.search.SearchPhaseExecutionException: all shards failed"

然后又出现一句

Cluster health status changed from [RED] to [GREEN] (reason: [shards started [[.kibana_task_manager_1][0]]]).

请问出现这样的日志会有什么影响吗？每次启动都一堆报错觉得好慌。
