Anoop Sam John commented on HBASE-19386:
----------------------------------------
bq.// java.nio.Bits.unaligned() wrongly returns false on ppc (JDK-8165231),
We had this.. So the JDK bug u refer here, can u link that too here pls? Also
write abt that ref in the code where u have done the fix. Easy later to read
and understand why the hard coded checks
> HBase UnsafeAvailChecker returns false on Arm64

> Arm64v8 supports unaligned access .
> But UnsafeAvailChecker returns false due to a JDK bug.
> The false of UnsafeAvailChecker return also causes the HBase Unit
> tests(FuzzyRowFilter, TestFuzzyRowFilterEndToEnd,
> TestFuzzyRowAndColumnRangeFilter) failures.
> Enable Arm64 unaligned support by providing a hard-code workaround for the
> JDK bug.
