Got fatal error 1236 from master when reading data from binary log

In case your Mysql or Mariadb replication crashed with following error, here are steps we do to recover replication:

Got fatal error 1236 from master when reading data from binary log: 'Client requested master to start replication from impossible position; the first event 'mysql-bin.006270' at 357275228, the last event read from 'mysql-bin.006270' at 4, the last byte read from 'mysql-bin.006270' at 4.'

In our case was the root of problem crash of master server, therefore the slave didn't finish reading of binary log and stopped replicating.
This was the state in our slave, when on master was corrupted mysql-bin.006270:

Solution in our case was to change master log file to next bin log file mysql-bin.006271 from position 4 and start slave again:

stop slave;

CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.006271', MASTER_LOG_POS=4;

start slave;
