> Empty ORC file handling
> -----------------------
>
> Key: HIVE-8137
> URL: https://issues.apache.org/jira/browse/HIVE-8137
> Project: Hive
> Issue Type: Improvement
> Components: File Formats
> Affects Versions: 0.13.1
> Reporter: Pankit Thapar
> Fix For: 0.14.0
>
> Attachments: HIVE-8137.2.patch, HIVE-8137.patch

>
> Hive 13 does not handle reading of a zero size Orc File properly. An Orc file
> is suposed to have a post-script
> which the ReaderIml class tries to read and initialize the footer with it.
> But in case, the file is empty
> or is of zero size, then it runs into an IndexOutOfBound Exception because of
> ReaderImpl trying to read in its constructor.
> Code Snippet :
> //get length of PostScript
> int psLen = buffer.get(readSize - 1) & 0xff;
> In the above code, readSize for an empty file is zero.
> I see that ensureOrcFooter() method performs some sanity checks for footer ,
> so, either we can move the above code snippet to ensureOrcFooter() and throw
> a "Malformed ORC file exception" or we can create a dummy Reader that does
> not initialize footer and basically has hasNext() set to false so that it
> returns false on the first call.
> Basically, I would like to know what might be the correct way to handle an
> empty ORC file in a mapred job?
> Should we neglect it and not throw an exception or we can throw an exeption
> that the ORC file is malformed.
> Please let me know your thoughts on this.
