-------------------------------------
Summary: Sporadic java.net.ConnectException: Connection refused
when connecting to :19002/aql
Key: ASTERIXDB-1924
URL: https://issues.apache.org/jira/browse/ASTERIXDB-1924
Project: Apache AsterixDB
Issue Type: Bug
Reporter: Taewoo Kim
I am using bigFUN benchmark to send queries to AsterixDB instance located on
the sensorium cluster. After creating this instance using the latest master, a
connection to sensorium-11.ics.uci.edu:19002/aql is sporadically rejected.
