Chia-Ping Tsai commented on HBASE-16814:
----------------------------------------
unsafe reference :
http://www.javaworld.com/article/2952869/java-platform/understanding-sun-misc-unsafe.html
If the unsafe is disabled, FuzzyRowFilter will fail and may cause timeout
because the FuzzyRowFilter#getNextForFuzzyRule returns the wrong result which
causes the stuck in a while loop. (see FuzzyRowFilter.RowTracker#updateTracker)
We try to fix FuzzyRowFilter in HBASE-17890.
