> We try to roll logs because can't append (See HDFS-8960) but we get stuck. See attached
thread dump and associated log. What is interesting is that syncers are waiting to take syncs
to run and at same time we want to flush so we are waiting on a safe point but there seems
to be nothing in our ring buffer; did we go to roll log and not add safe point sync to clear
out ringbuffer?
> Needs a bit of study. Try to reproduce.
