Subject [jira] [Created] (YARN-1219) FSDownload changes file suffix making FileUtil.unTar() throw exception

---------------------------------

             Summary: FSDownload changes file suffix making FileUtil.unTar() throw exception
                 Key: YARN-1219
                 URL: https://issues.apache.org/jira/browse/YARN-1219
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 3.0.0, 2.1.1-beta
            Reporter: shanyu zhao


While running a Hive join operation on Yarn, I saw exception as described below. This is caused
by FSDownload copy the files into a temp file and change the suffix into ".tmp" before unpacking
it. In unpack(), it uses FileUtil.unTar() which will determine if the file is "gzipped" by
looking at the file suffix:
{code}
boolean gzipped = inFile.toString().endsWith("gz");
{code}

To fix this problem, we can remove the ".tmp" in the temp file name.

Here is the detailed exception:
