What process do you use to determine what data is missing?  Are there
any patterns to the missing data? Do you have any iterators on your
tables?  Are you writing multiple versions (by defaults only one
version is kept and the others are dropped).  Are you setting the
visibility column?

Are you reusing or modify Mutation objects after you give them to the
batch writer?  The BatchWriter buffers them and writes them in the
background.  It creates a shallow copy when you give it a mutation.
