Yi Tian commented on SPARK-3324:
--------------------------------
I think the deeper problem is the codes in common and stable depends each
other, we should combine these codes to single project or redefine the
relations of these two parts of codes.
> YARN module has nonstandard structure which cause compile error In IntelliJ

> Key: SPARK-3324
> URL: https://issues.apache.org/jira/browse/SPARK-3324
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Affects Versions: 1.1.0
> Environment: Mac OS: 10.9.4
> IntelliJ IDEA: 13.1.4
> Scala Plugins: 0.41.2
> Maven: 3.0.5
> Reporter: Yi Tian
> Assignee: Patrick Wendell
> Priority: Minor
> Labels: intellij, maven, yarn
>
> The YARN module has nonstandard path structure like:
> {code}
> ${SPARK_HOME}
> |--yarn
> |--alpha (contains yarn api support for 0.23 and 2.0.x)
> |--stable (contains yarn api support for 2.2 and later)
> | |--pom.xml (spark-yarn)
> |--common (Common codes not depending on specific version of Hadoop)
> |--pom.xml (yarn-parent)
> {code}
> When we use maven to compile yarn module, maven will import 'alpha' or
> 'stable' module according to profile setting.
> And the submodule like 'stable' use the build propertie defined in
> yarn/pom.xml to import common codes to sourcePath.
> It will cause IntelliJ can't directly recognize sources in common directory
> as sourcePath.
> I thought we should change the yarn module to a unified maven jar project,
> and add specify different version of yarn api via maven profile setting.
> It will resolve the compile error in IntelliJ and make the yarn module more
> simple and clear.
