EsRejectedExecutionException in ES

(Kennedy Kan) #1

My ES has been running fine. However, after I have managed to run through a visualization chart which gone through a large amount of data, it gives me the following error.

EsRejectedExecutionException[rejected execution of org.elasticsearch.transport.TransportService$4@9474a on EsThreadPoolExecutor[search, queue capacity = 1000, org.elasticsearch.common.util.concurrent.EsThreadPoolExecutor@1aa8ac1[Running, pool size = 4, active threads = 4, queued tasks = 1000, completed tasks = 7289]]]

Does that mean I have too many data for loading which the ES could not hold up to this amount?

It's not necessarily an indication that you have too much data, but that you are overwhelming the Elasticsearch instance with too many requests. A few options are to increase the size of the queue or threadpool, or add more nodes to the cluster.

Hi @tsmalley,

Thanks. But I am not sure how I should increase the queue size or thread pool.

Can I just directly add to elasticsearch.yml with this?

threadpool.bulk.type: fixed
threadpool.bulk.size: 8
threadpool.bulk.queue_size: 10000
