------------------------------------
[~vanzin] Yes, you are right! Thank you very much! But why setReadable doesn't
work as root?
> FsHistoryProviderSuite failed because setReadable doesn't work in RedHat

> Components: Spark Core

> FsHistoryProviderSuite failed in case "SPARK-3697: ignore files that cannot
> be read.". I try to invoke logFile2.canRead after invoking
> "setReadable(false, false)" . And I find that the result of
> "logFile2.canRead" is true but in my ubuntu16.04 return false.
