------------------------------
Assignee: shanyu zhao
> 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
> Assignee: 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:
> org.apache.commons.compress.archivers.tar.TarArchiveInputStream.getNextTarEntry(TarArchiveInputStream.java:240)
