问题描述
我收到ElasticsearchStatusWarning的消息，说集群状态为黄色。运行运行状况检查API后，我将看到以下内容
卷曲-X GET http：// localhost：9200 / _cluster / health /
{"cluster_name":"my-elasticsearch","status":"yellow","timed_out":false,"number_of_nodes":8,"number_of_data_nodes":3,"active_primary_shards":220,"active_shards":438,"relocating_shards":0,"initializing_shards":2,"unassigned_shards":0,"delayed_unassigned_shards":0,"number_of_pending_tasks":0,"number_of_in_flight_fetch":0,"task_max_waiting_in_queue_millis":0,"active_shards_percent_as_number":99.54545454545455}
initializing_shards是2。所以，我进一步运行以下调用
卷曲-X GET http：// localhost：9200 / _cat / shards？h = index，shard，prirep，state，unssigned.reason | grep INIT
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 33457 100 33457 0 graph_vertex_24_18549 0 r INITIALIZING ALLOCATION_Failed
0 79609 0 --:--:-- --:--:-- --:--:-- 79659
卷曲-X GET http：// localhost：9200 / _cat / shards / graph_vertex_24_18549
graph_vertex_24_18549 0 p STARTED 8373375 8.4gb IP1 elasticsearch-data-1
graph_vertex_24_18549 0 r INITIALIZING IP2 elasticsearch-data-2
并在几分钟后重新运行同一命令，显示现在它已在elasticsearch-data-0中初始化。见下文
graph_vertex_24_18549 0 p STARTED 8373375 8.4gb IP1 elasticsearch-data-1
graph_vertex_24_18549 0 r INITIALIZING IP0 elasticsearch-data-0
如果我在几分钟后再次运行它，我可以看到它再次在elasticsearch-data-2中初始化。但是它永远不会开始。

由于与上述相同的异常，我较早收到未分配碎片的警报-“ CircuitBreakingException [[parent]数据太大，[
但是那时候堆只有2G。我将其增加到4G。现在我看到了同样的错误，但是这次是关于初始化分片而不是未分配的分片。
我该如何补救？
