>                 Key: SPARK-2970
>                 URL: https://issues.apache.org/jira/browse/SPARK-2970
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 1.1.0
>         Environment: CDH5.1.0 (Hadoop 2.3.0)
>            Reporter: Kousuke Saruta
>
> When spark-sql script run with spark.eventLog.enabled set true, it ends with IOException
because FileLogger can not create APPLICATION_COMPLETE file in HDFS.
> I think it's because FIleSystem is closed by HiveSessionImplWithUGI.
> It has a code as follows.
> {code}
>   public void close() throws HiveSQLException {
>     try {
>     acquire();
>     ShimLoader.getHadoopShims().closeAllForUGI(sessionUgi);
>     cancelDelegationToken();
>     } finally {
>       release();
>       super.close();
>     }
>   }
> {code}
> When using Hadoop 2.0+, ShimLoader.getHadoopShim above returns Hadoop23Shim which extends
HadoopShimSecure.
> HadoopShimSecure#closeAllForUGI is implemented as follows.
> {code}
>   @Override
>   public void closeAllForUGI(UserGroupInformation ugi) {
>     try {
>       FileSystem.closeAllForUGI(ugi);
>     } catch (IOException e) {
>       LOG.error("Could not clean up file-system handles for UGI: " + ugi, e);
>     }
>   }
> {code}
