-----------------------------
Summary: Sporadic JDBC connection failure (Drill 1.10)
Key: DRILL-5455
URL: https://issues.apache.org/jira/browse/DRILL-5455
Project: Apache Drill
Issue Type: Bug
Environment: JDK 1.7
Reporter: Rakesh
My invocation to get JDBC connection succeeds 8 out of 10 times and fails the
other times with the below message. (Of course it's not predictable or
reproducible hence don't know the circumstances to reproduce it):
JavaException: ../quartz/src/javapy/JavaPy.cpp:449: JavaException:
java.sql.SQLException: Failure in connecting to Drill:
oadd.org.apache.drill.exec.rpc.RpcException: Failure setting up ZK for client.
