[jira] [Updated] (HADOOP-7824) Native IO uses wrong constants almost everywhere

     [ https://issues.apache.org/jira/browse/HADOOP-7824?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Martin Walsh updated HADOOP-7824:
---------------------------------
    Attachment: HADOOP-7824.001.patch

Changes introduce checkstyle issues.  This is because for the JNI solution to work the constants we modify the value for must have the "final" modifier removed.  Checkstyle then thinks this is a standard variable and applies a different ruleset to it.
