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

[~sershe] Actually it is a duplicated issue. SameĀ as [HIVE-18219|https://issues.apache.org/jira/browse/HIVE-18219]

>                 URL: https://issues.apache.org/jira/browse/HIVE-19393
>             Project: Hive
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 1.0.0
>            Reporter: John Doe
>            Priority: Minor
>
> When an InputStream is corrupted, the InputStream.skip can return -1, causing the while
loop in NonSyncDataInputBuffer.skipBytes become infinite.
> {code:java}
>   public final int skipBytes(int count) throws IOException {
>     int skipped = 0;
>     long skip;
>     while (skipped < count && (skip = in.skip(count - skipped)) != 0) {
>       skipped += skip;
>     }
>     if (skipped < 0) {
>       throw new EOFException();
>     }
>     return skipped;
>   }
> {code}
> Similar bugs are Hadoop-8614, Yarn-2905, Yarn-163, Mapreduce-6990
