I already took a look at the answers at: ERROR 1066: Unable to open iterator for alias - Pig But they don't help me. My environment: OS: Windows 7 Pig version: http://stackoverflow.com/questions/28122311/error-1066-unable-to-open-iterator-for-alias 0.13.0 Mode: Local It shows in the error that the exception is 'Caused by' a failure to change permission of a file in the TMP directory. But when I checked the TMP directory, there's no such file (probably it got deleted after the command is finished?).
