-------------------------------
Summary: Remove usage of sun.misc.Unsafe
Key: HADOOP-19334
URL: https://issues.apache.org/jira/browse/HADOOP-19334
Project: Hadoop Common
Issue Type: Bug
Reporter: yanmin
when we build hadoop in JDK11 runtime based on
[https://github.com/apache/hadoop/pull/7085,] JDK11 build is failing as flowing
due to: {{package sun.misc does not exist}} in.
This is because that package sun.misc is not supported after jdk11.
The purpose of this JIRA is to replace the .misc.Unsafe.
