      Description

      While running a Java 8 compiled hbase on Java 11 system, I found the following warnings being thrown. I think we can add the "--add-opens" flag to HBASE_OPTS (if the jdk version is 11) to suppress this warning.

      WARNING: An illegal reflective access operation has occurred
      WARNING: Illegal reflective access by org.apache.hadoop.hbase.util.UnsafeAvailChecker (file:/Users/jatsakthi/test/HBASE_TEST_AREA/hbase-3.0.0-SNAPSHOT/lib/hbase-common-3.0.0-SNAPSHOT.jar) to method java.nio.Bits.unaligned()
      WARNING: Please consider reporting this to the maintainers of org.apache.hadoop.hbase.util.UnsafeAvailChecker
      WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
      WARNING: All illegal access operations will be denied in a future release
