This is because in Hadoop 2, the {{copyToLocal}} maps to 2 underlying {{RawLocalFileSystem}} operations: {{create}} and {{setPermission}}. On an SMB share, the user may be authorized for the {{create}} but denied for the {{setPermission}}. Windows denies the {{WRITE_DAC}} right required by {{setPermission}} unless the user has Full Control permissions. Granting Full Control isn't feasible for most deployments, because it's insecure. This is a regression from Hadoop 1, where {{copyToLocal}} only did a {{create}} and didn't do a separate {{setPermission}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
