Terry Wang commented on FLINK-15055:
------------------------------------

It indeed confuses me a lot that all my PRs Travis build failed due to this issue. + 1 to fix soon.

> According to FLINK-14630, in order to properly generate logs, test cases that use starts cluster with YarnClusterDescriptor on MiniYARNCluster should call the util function FlinkYarnSessionCli#setLogConfigFileInConfig to set the path of log4j property file into the configuration.
> The YarnDistributedCacheITCase failed to do this.
> We probably should also revisit other Yarn IT cases see if there's any other case that also failed to do this. 
> A discussable alternative is to make it a default behavior for YarnClusterDescriptor to always set the default log4j property file, if it can find one, when the property file is not explicitly configured.
