> MiniYarnCluster specifies individual remote log aggregation root dir for each
> NM. Test code that uses MiniYarnCluster won't be able to get the value of log
> aggregation root dir. The following code isn't necessary in MiniYarnCluster.
> File remoteLogDir =
> new File(testWorkDir, MiniYARNCluster.this.getName()
> + "-remoteLogDir-nm-" + index);
> remoteLogDir.mkdir();
> config.set(YarnConfiguration.NM_REMOTE_APP_LOG_DIR,
> remoteLogDir.getAbsolutePath());
> In LogCLIHelpers.java, dumpAllContainersLogs should pass its conf object to
> FileContext.getFileContext() call.
