SammiChen commented on HADOOP-14964:


Hi [~chris.douglas], I see the problem now.  Thanks for such detail 
information. Let's wait for LEGAL's opinion. In the meanwhile, we will look 
into alternatives libraries to replace json-lib.  Also thanks @Junping Du for 
considering landing this feature into 2.8.3.  I agree we should go ahead to cut 
2.8.3 CR0.

> Reported in SPARK-21137. a {{FileSystem.listStatus}} call really craws 
> against the local FS, because {{FileStatus.getPemissions}} call forces  
> {{DeprecatedRawLocalFileStatus}} tp spawn a process to read the real UGI 
> values.
> That is: for every other FS, what's a field lookup or even a no-op, on the 
> local FS it's a process exec/spawn, with all the costs. This gets expensive 
> if you have many files.
