Critical Description
There is a possible dataloss scenario
when using JBOD,
when moving the partition leader log from one directory to another on the same broker,
when after the destination log has caught up to the source log and after the broker has sent an update to the partition assignment
if the broker accepts and commits a new record for the partition and then the broker restarts and the original partition leader log is lost
then the destination log would not contain the new record.
