---------------------------------------
Summary: Incorrect decision of host unavailable in Java client
Key: TINKERPOP-2176
URL: https://issues.apache.org/jira/browse/TINKERPOP-2176
Project: TinkerPop
Issue Type: Bug
Components: driver
Affects Versions: 3.3.5, 3.4.0
Reporter: Divij Vaidya
If a request is not able to acquire a connection from the connection pool for a
particular duration, it will fail with a Timeout Exception and also mark the
host as unreachable [1] which is not necessarily true. A request might not be
able to get a connection from the pool because the pool configuration has been
set to a very low number or all the connections are genuinely busy serving
existing requests. It does not imply host being unreachable.
