Igniters, I faced a problem with iterate over WAL.
Let's imagine that we write WAL and write some record which depends from ignite-index. And then move files to another machine, which does not have ignite-index in the classpath. Now try to iterate over WAL. If iterator can not deserialize some record he try to go next and execute advanceSegment() for switching to the next segment. (ignite-index not in the classpath) 1. Iterator skips part of the WAL because advanceRecord() failed to deserialize record. 2. Iterator does not signal that there was an error. In my opinion, it is not that we expected. Any comments?
