Nicolas Thiébaud updated HBASE-6725:
------------------------------------
Description:
When multiple threads race using CAP with and a lock on the same row, several
instances may be allowed to update the cell with the new value (although the
expected value is different).
If all threads race with a wrong expected value and a lock, none will be able
to update.
was:When using CAP with an empty array as expected value and using a lock on
the corresponding row, hbase may allow a Put even if the value was already
there.
> Check and Put can fail when using locks
