Hi guys,
We are experiencing an issue with communication between our program and elastic-search cloud server. We are using jdbc importer to transfer data to elastic-search from local database. Jdbc importer is a Java based program which guarantees a complete transfer of data.
We are unable to establish connection to cloud system. This is due to a failed request of getting a node info, which disconnecting our program from server. More detailed information can be found in Exception #1 below. This results in an error that causes our program to fail. This error is due to availability of nodes. More detailed information about the error can be found in Exception #2.
Exception #1: NodeDisconnectedException
[INFO][org.elasticsearch.org.xbib.elasticsearch.helper.client.TransportClient][pool-3-thread-1] [importer] failed to get node info for {#transport#-1}{50.16.191.15}{49a470021ebdb61e456ccae825b9adcd.us-east-1.aws.found.io/50.16.191.15:9343}, disconnecting...

Exception #2: NoNodeAvailableException

We are wondering how to fix the problem, how to establish a valid connection to the cloud server through using jdbc importer?
