During some recovery testing and also testing for SpillableMemoryChannel. I encountered some problem like this (which use 1.7 snapshot)

we can simply reproduce such as follows:
1. start flume with channel and sink configuration
2. run some time to let such deliver data from source to sink destination e.g elastic search
3. change the conf configuration and make the sink node to be some wrong address and then
it would show connection refused for the sink
4. delivering data to be continue as usual like 2nd step for some time
5. recovery the sink address to the be right one and watch whether the whole flow could be recovered as usual. and you will get the stack trace as above.
By the way, I don't know why it continue to show the nullpointerException by creating the createTransaction while recovering.
hope flume team could pay more attention to the stability of channel e.s.p for the SpillableMemoryChannel one and better improve the exception control
