Response indexing using JAVA API

Elastic Stack Elasticsearch
1

Hi, Guys.
We are using response JAVA API
We posted 50,000 line on Elasticsearch via Java API.
We are seeing Transport error some times.

We get following error some times.

org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: []
at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:305)
at org.elasticsearch.client.transport.TransportClientNodesService.execute(TransportClientNodesService.java:200)

at sample1.ESsample.response_Index(ESsample.java:191)
at sample1.Es_test.main(Es_test.java:732)

Why I got this error?
I assumed that this error occurred after excessive posting of indexing data.
This error rarely occurred after memory extension.

but then, I finished pushing all data on Elasticsearch via JAVA API.
following error ocured.

java.sql.SQLRecoverableException: KFPA11723-E Communication error occurred, reason=NETWORK[PrdbConnection.commit][HiRDB_CONNECTION_ID(fes:4316:12188)]

at sample1.hirdb_connect.close(hirdb_connect.java:56)

Why I got this error?
I assumed that this error occurred early close connection while posting date on Elasticsearch.
How can I posted all date on Elasticsearch without above error.

sincerely.

Yes, your cluster disconnected, mostly because it can not respond within 5 seconds. A larger cluster can handle your data better or you should reconsider if sending 50.000 lines at one is a good ides. If you send smaller amount and give the cluster time, it will work much better.

This is not the right forum to discuss SQL messages.

The message is a SQLRecoverableException so you can repeat the close action until it succeeds.
