Thejas M Nair commented on HIVE-11915:
--------------------------------------

Thanks for the update. Can you also update the log message to also indicate that there is
going to be a retry ? Otherwise, users might not realize that the issue was not fatal. Also,
please update it to include the full exception stack trace. That can be very useful for debugging.

> It's a very old bug in BoneCP and it will never be fixed... There are multiple workarounds
on the internet but according to responses they are all unreliable. We should upgrade to HikariCP
(which in turn is only supported by DN 4), meanwhile try some shamanic rituals. In this JIRA
we will try a relatively weak drum.
