Subject [Hadoop Wiki] Trivial Update of "HCFS/FileSystem-2.0-Tests" by JayVyas

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "HCFS/FileSystem-2.0-Tests" page has been changed by JayVyas:
https://wiki.apache.org/hadoop/HCFS/FileSystem-2.0-Tests?action=diff&rev1=4&rev2=5

+ 
+ There are essentially 2 major types of tests in this package which are relevant to the HCFS
working group.  
+ 1) Those that exercise the FileSystem and
+ 2) Those that exercise the new AbstractFileSystem.

+ == FileSystem Tests ==
  
  These tests build off of the  [[HCFS/FileSystem-1.0-Tests|FileSystem-1.0]] test library.

+ == Conclusions ==
  
+ Hadoop 2.X adds several new tests and the FileContext related tests provide extension points
for other HCFS tests.
+ 
+ This is an initial analysis.  Comparison of missing tests would be much appreciated.  
+ 
+ We have used the JDiff tool to diff between 1.X (1.1) and the 2.X branches (2.1-beta) and
summarized classes by inspection in order to identify the ability to generalize these tests,
but this may be prone to error.  Comments and/or edits are welcome.
