> Key: OOZIE-2844
> URL: https://issues.apache.org/jira/browse/OOZIE-2844
> Project: Oozie
> Issue Type: Improvement
> Components: action
> Affects Versions: 4.3.0
> Reporter: Andras Piros
> Assignee: Andras Piros

> In several Oozie actions we face the problem that if {{log4j.properties}} is
> not readable by current thread, or not present on the classpath, while taking
> an {{URL.openStream()}} call afterwards, an {{IOException}} is thrown and the
> action won't run.
> Such actions are:
> *
> [*{{DistcpMain}}*|https://github.com/apache/oozie/blob/master/sharelib/distcp/src/main/java/org/apache/oozie/action/hadoop/DistcpMain.java#L135]
> *
> [*{{HiveMain}}*|https://github.com/apache/oozie/blob/master/sharelib/hive/src/main/java/org/apache/oozie/action/hadoop/HiveMain.java#L146]
> *
> [*{{PigMain}}*|https://github.com/apache/oozie/blob/master/sharelib/pig/src/main/java/org/apache/oozie/action/hadoop/PigMain.java#L173]
> *
> [*{{PigMainWithOldApi}}*|https://github.com/apache/oozie/blob/master/sharelib/pig/src/main/java/org/apache/oozie/action/hadoop/PigMainWithOldAPI.java#L160]
> *
> [*{{SparkMain}}*|https://github.com/apache/oozie/blob/master/sharelib/spark/src/main/java/org/apache/oozie/action/hadoop/SparkMain.java#L430]
> *
> [*{{SqoopMain}}*|https://github.com/apache/oozie/blob/master/sharelib/sqoop/src/main/java/org/apache/oozie/action/hadoop/SqoopMain.java#L124]
> Extend
> [*{{LauncherMain.run()}}*|https://github.com/apache/oozie/blob/master/sharelib/oozie/src/main/java/org/apache/oozie/action/hadoop/LauncherMain.java#L62-L65]
> by a convenience method that loads Hadoop's {{log4j.properties}} in
> beforehand. In case {{URL.openStream()}} would throw {{IOException}} we
> resort to a call to a new file {{hadoop-default-log4j.properties}} on the
> classpath (packaged along w/ {{LauncherMain.class}}) that has the same
> contents as the {{log4j.properties}} that is not accessible / readable /
> present.
