[jira] [Closed] (TINKERPOP3-746) Investigate WARN Message in Driver
[ https://issues.apache.org/jira/browse/TINKERPOP3-746?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
stephen mallette closed TINKERPOP3-746.
---------------------------------------
Resolution: Fixed
Fixed this one via:
https://github.com/apache/incubator-tinkerpop/commit/cb7db410ff3d22e20b57313c33f5886cad87c7ca
Logs are much more clear without that nagging error. Basically, background threads in the driver were trying to do a reconnect after calls to {{Cluster.close()}}.
