Phabricator updated HIVE-1444:
------------------------------

    Attachment: HIVE-1444.D1839.1.patch

edwardcapriolo requested code review of "HIVE-1444 [jira] "hdfs" is hardcoded 
in few places in the code which inhibits use of other file systems".
Reviewers: JIRA

  https://issues.apache.org/jira/browse/HIVE-1444

  Allows other fs implementations then HDFS

  In quite a few places "hdfs" is hardcoded, which is OK for majority of the 
cases, except when it is not really hdfs, but s3 or any other file system.

  The place where it really breaks is:
  in ql/src/java/org/apache/hadoop/hive/ql/parse/LoadSemanticAnalyzer.java :

  method: private void applyConstraints(URI fromURI, URI toURI, Tree ast, 
boolean isLocal)

  First few lines are check for file system:
      if (!fromURI.getScheme().equals("file")
          && !fromURI.getScheme().equals("hdfs")) {
        throw new SemanticException(ErrorMsg.INVALID_PATH.getMsg(ast,
            "only \"file\" or \"hdfs\" file systems accepted"));
      }

  "hdfs" is hardcoded.

  I don't think you need to have this check at all as you are checking whether 
filesystem is local or not later on anyway and in regards to non locla file 
system - if one would be bad one you would get problems or have it look like 
local before you even come to "applyConstraints" method.
