[jira] [Created] (HADOOP-12690) Consolidate access of
sun.misc.Unsafe
Junping Du created HADOOP-12690:
-----------------------------------
Summary: Consolidate access of sun.misc.Unsafe
Key: HADOOP-12690
URL: https://issues.apache.org/jira/browse/HADOOP-12690
Project: Hadoop Common
Issue Type: Bug
Reporter: Junping Du
Assignee: Junping Du
Per discussion in Hadoop-12630 (https://issues.apache.org/jira/browse/HADOOP-12630?focusedCommentId=15082142&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15082142), we found the access of sun.misc.Unsafe could be problematic for some JVMs in other platforms. Also, hints from other comments, it is better to consolidate it as a helper/utility method to shared with several places (FastByteComparisons, NativeIO, ShortCircuitShm).
