    Attachment: YARN-1751.patch

Thanks, Jason. Here is the patch for MiniYarnCluster.

I have opened https://issues.apache.org/jira/browse/YARN-2050 for the LogCLIHelpers issue
and will post more comments there.

> 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.
