[jira] [Created] (HBASE-19386) HBase UnsafeAvailChecker returns false on Arm64

Yuqi Gu created HBASE-19386:
-------------------------------

             Summary: HBase UnsafeAvailChecker returns false on Arm64
                 Key: HBASE-19386
                 URL: https://issues.apache.org/jira/browse/HBASE-19386
             Project: HBase
          Issue Type: Bug
    Affects Versions: 3.0.0
            Reporter: Yuqi Gu
            Priority: Minor


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 access by providing a hard-code workaround for the JDK bug.
