> We are running an integration test in which we start an Embedded Connect Cluster in the active 3.5 branch. However, because of transient disk error, we may encounter an IOException during appending records to one topic. As shown in the stack trace:

> I am wondering if we could add configurable retry around the root cause to tolerate the possible I/O faults so that if the retry is successful, the embedded connect cluster could still operate. 
> Any comments and suggestions would be appreciated.
