Yiqun Lin commented on HDFS-14082:
----------------------------------
{quote}Then, I would keep it backwards compatible setting it to true.
{quote}
The default value should be false i think. We are allowed to get partial list
when someone subcluster is unavailable by default.
{quote}What do you propose here? We definetely can make 6 a variable but not
sure about 4/5.
{quote}
I mean we make following change and not use specific number.
{code:java}
// Test the behavior when everything is fine
+ FileSystem fs = getRouterFileSystem();
+ FileStatus[] files = fs.listStatus(new Path("/"));
int originalCount= files.length
,,,,
// simplify the assertion logic
assertNotEqual("...", originalCount , files.length);
{code}
