Review comment:
If a user requests STDOUT and then LOG, he will not get STDOUT twice.
As `fileBlobKeys` is not static, so it's belonging to its object. And I have
tested it by：
```java
log.info(String.format("fileBlobKeys [%s] cached file for TaskExecutor [%s]
taskManagerId [%s], blobKey [%s]", fileBlobKeys.toString(),
taskManagerIdAndFileName, taskManagerId, blobKey.toString()));
```
The result is：
