FileSystem cache should be case-insensitive
-------------------------------------------
Key: HADOOP-3785
URL: https://issues.apache.org/jira/browse/HADOOP-3785
Project: Hadoop Core
Issue Type: Bug
Reporter: Doug Cutting
Fix For: 0.19.0
We cache FileSystem instances based on URI scheme & authority, plus username.
Elsewhere we compare URI schemes and authorities case-insensitively, but the
cache is case-sensitive. In particular, the Cache.Key#equals() and
Cache.Key#hashCode() should be made case-insensitive.
This should not be a blocker, since the worst it causes is a few extra
FileSystem instances to be cached.
