Subject [jira] [Commented] (HADOOP-13092) RawLocalFileSystem is not case sensitive
Date Tue, 10 May 2016 08:50:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15277819#comment-15277819
] 

Andras Bokor commented on HADOOP-13092:
---------------------------------------

Based on the following code I will set case sensitivity to false on Windows and Mac:

{code:title=LocalFSContract.java}
protected void adjustContractToLocalEnvironment() {
    if (Shell.WINDOWS) {
      //NTFS doesn't do case sensitivity, and its permissions are ACL-based
      getConf().setBoolean(getConfKey(ContractOptions.IS_CASE_SENSITIVE), false);
      getConf().setBoolean(getConfKey(ContractOptions.SUPPORTS_UNIX_PERMISSIONS), false);
    } else if (ContractTestUtils.isOSX()) {
      //OSX HFS+ is not case sensitive
      getConf().setBoolean(getConfKey(ContractOptions.IS_CASE_SENSITIVE),
                           false);
    }
  }
{code}

> RawLocalFileSystem is not case sensitive but I am not sure if it should be.
> This class relays on the underlying OS filesystem so if it runs on a non case sensitive
OS the class will be insensitive as well.
> On Mac follow the following commands:
> # echo asdf > lower.txt
> # cat loWer.txt
> Do we need to make RawLocalFileSystem class case sensitive? Please help.
