Subject Failed to reconnecting to IBM MQ using Flume JMS source
Date Tue, 13 Jun 2017 02:00:22 GMT
Hi Everyone,
Does anyone get an issue of reconnecting to IBM MQ using Flume JMS source ?

Steps to reproduce:
1. Stop MQ service (I use IBM MQ Docker)
2. Start flume agent with JMS source using MQ .bindings
3. Start MQ service.
4. You will see the issue with Flume JMS could not reconnect when MQ
service come back to work.

Note that Flums JMS works fine when MQ service is ready before starting
Flume agent.

Please give me your ideas on this issue ?
