Hi, all.  
Using elasticsearch-spark to write data to elasticsearch throws exception: There are 8 nodes in my cluster. Through monitoring, we see that the pressure of the cluster is not large and the machine load is good.

The exception information is as follows:

Job aborted due to stage failure: Task 7 in stage 0.0 failed 4 times, most recent failure: Lost task 7.3 in stage 0.0 (TID 32, [slave777-prd3.sss.com](http://slave777-prd3.sss.com), executor 10): org.apache.spark.util.TaskCompletionListenerException: Connection error (check network and/or proxy settings)- all nodes failed; tried [[10.247.24.51:9100, 10.101.10.131:9100, 10.247.24.52:9100, 10.101.10.130:9100, 10.247.24.55:9100, 10.247.24.54:9100, 10.101.10.132:9100, 10.247.24.53:9100]] +details
