Raghu Angadi commented on HADOOP-5191:
--------------------------------------
This does not seem like an AIX or Solaris issue. Fix should work work for ips
as well as aliases if there is one.
This goes to basics of what "fs.default.name" means. If a canonical for for
comparing makes sense according to its definition, then we should do it
properly (for e.g. how are multiple ips handled, or aliases handled as Bo Shi
mentioned).
Do we have a definition or meaning of "fs.default.name"?
This issue has come up multiple times and deserves either a fix or a
clarification.
regd patch : please avoid referring jiras in the code as much as possible.. it
is ok to 'waste space' with slightly longer justifications in the code.
