-----------------------------------

bq. after the log is released
I guess you meant 'after the lock is released'
                
> Avoid holding the rowlock during HLog sync in HRegion.mutateRowWithLocks

> Currently mutateRowsWithLocks holds the row lock while the HLog is sync'ed.
> Similar to what we do in doMiniBatchPut, we should create the log entry with 
> the lock held, but only sync the HLog after the log is released, along with 
> rollback logic in case the sync'ing fails.
