[jira] [Commented] (YARN-358) bundle container classpath in
temporary jar on all platforms, not just Windows
[ https://issues.apache.org/jira/browse/YARN-358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15263690#comment-15263690 ]
Shuai Zhang commented on YARN-358:
----------------------------------
I found it difficult to work with DockerContainerExecutor. The environment is different within a Docker container or not, so the classpath differs according to the environment variables such as HADOOP_PREFIX, YARN_CONF_DIR, etc. We cannot introduce environment variables within a Docker container into a generated manifest file. As a result, we cannot generate a correct manifest file running within a Docker container.

> Currently, a Windows-specific code path bundles the classpath into a temporary jar with a manifest to work around command line length limitations. This code path does not need to be Windows-specific. We can use the same approach on all platforms.
