Rishindra Kumar updated FLINK-13689:
------------------------------------
Description:
If the created Elastic Search Rest High Level Client(rhlClient) is unreachable,
Current code throws RuntimeException. But, it doesn't close the client which
causes thread leak.
*Current Code*
*if (!rhlClient.ping()) {*
*throw new RuntimeException("There are no reachable Elasticsearch
nodes!");*
*}*
*Change Needed*
rhlClient needs to be closed.
*Steps to Reproduce*
1. Add the ElasticSearch Sink to the stream. Start the Flink program without
starting the ElasticSearch.
2. Program will give error: "*Too many open files*" and it doesn't write even
though you start the Elastic Search later.
