------------------------------
Summary: 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
Priority: Minor
The YARN module has nonstandard path structure like:
${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)
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 recogniz codes in common directory as
sourcePath.
I thought we should change the yarn module to a unified maven jar project,
and choose the version of yarn api via maven profile setting in the pom.xml.
It will resolve the compile error in IntelliJ and make the yarn module more
simple and clear.
