[jira] [Commented] (MAPREDUCE-5442)
$HADOOP_MAPRED_HOME/$HADOOP_CONF_DIR setting not working on Windows
[ https://issues.apache.org/jira/browse/MAPREDUCE-5442?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13758076#comment-13758076 ]
Chuan Liu commented on MAPREDUCE-5442:
--------------------------------------
[~yingdachen], can we make DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH have different values for different OSes instead of creating two constants as in the following code?
{code:java}
- public static final String[] DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH = {
- "$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/*",
- "$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/lib/*",
- };
+ public static final String
+ DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH =
+ "$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/*,"
+ + "$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/lib/*";
+
+ /**
+ * Default CLASSPATH for all YARN MapReduce applications on Windows.
+ */
+ public static final String
+ DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH_ON_WINDOWS =
+ "%HADOOP_MAPRED_HOME%\\share\\hadoop\\mapreduce\\*,"
+ + "%HADOOP_MAPRED_HOME%\\share\\hadoop\\mapreduce\\lib\\*";
{code}

> Currently the mapred-default.xml has "mapreduce.application.classpath" entry set to
> $HADOOP_MAPRED_HOME/share/hadoop/mapreduce/,$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/lib/
> which is problematic on Windows since the path does not work on Windows OS.
> Additionally, the yarn-default.xml has "yarn.application.classpath" entry that has similar problem, and is currently being tracked by YARN-1138
