Neha Narkhede commented on KAFKA-753:
-------------------------------------
I'm not too sure about this, but one way this can happen is if indexSlotFor()
returns a negative number (other than -1). It can return a negative number if
this operation overflows -
val mid = ceil(hi/2.0 + lo/2.0).toInt
This can lead to a negative physical position that gets passed into
messageSet.searchFor(offset, mapping.position) into translateOffset() and lead
to this error.
