Description

When follower wants to truncate partition and it is not allowed it prints the following message:

[2016-07-27 14:07:37,617] FATAL [ReplicaFetcherThread-0-19], Halting because log truncation is not allowed for topic rt3.fol--yabs-rt--bs-hit-log, Current leader 19's latest offset 50260815 is less
 than replica 2's latest offset 50260816 (kafka.server.ReplicaFetcherThread)

It is difficult to understand which partition is it.
I suggest to log here partition instead of topic. For example:

[2016-07-27 14:07:37,617] FATAL [ReplicaFetcherThread-0-19], Halting because log truncation is not allowed for partition [rt3.fol--yabs-rt--bs-hit-log,0], Current leader 19's latest offset 50260815 is less
 than replica 2's latest offset 50260816 (kafka.server.ReplicaFetcherThread)
