Hi,
I'm using Logstash 6.1 with the JDBC input plugin after upgrading from 5.2, and noticed a new behavior that was not there earlier.
Earlier when Logstash was not able to connect to the database or ran into an SQL error, it would terminate - which was fine for my use case, but with version 6.1 after the error it just attempts to restart the plugin with the errors:
Unable to connect to database. Tried 1 times {:error_message=>"Java::JavaSql::SQLRecoverableException: ORA-01033: ORACLE initialization or shutdown in progress\n"}
[ERROR][logstash.pipeline ] A plugin had an unrecoverable error. Will restart this plugin.
I tried searching for options but can't figure out if there is a way to limit the number of retries so that logstash terminates in case of such errors.
