mixing binlog formats between master and slave

I have a pretty much straightforward Master --> Slave replication setup in MySQL 5.6 / Innodb.

Both my Master and Slave are setup in MIXED binlog format.

Now I need my slave to act as a master to plug a Java binlog connector that will retrieve the binlog to further feed a hadoop stack. For this to work I have enabled the log-slave-updates variable

Thing is: that java connector will better work on row based binary log.

So my question is:

• Can I safely change the binlog format on my slave for ROW ?
• and keeping the MIXED format on the master ?

I Couldn't find any specifics about this in MySQL docs.
