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
