> The reason of the exception was that Hive was trying to read an empty
> manifest file. Manifest files are used in case of direct insert to determine
> which files needs to be kept and which one needs to be cleaned up. They are
> created by the tasks and they use the tast attempt Id as postfix. In this
> particular test what happened is that one of the container ran out of memory
> so Tez decided to kill it right after the manifest file got created but
> before the pathes got written into the manifest file. This was the manifest
> file for the task attempt 0. Then Tez assigned a new container to the task,
> so a new attemp was made with attemptId=1. This one was successful, and wrote
> the manifest file correctly. But Hive didn't know about this, since this out
> of memory issue got handled by Tez under the hood, so there was no exception
> in Hive, therefore no clean-up in the manifest folder. And when Hive is
> reading the manifest files, it just reads every file from the defined folder,
> so it tried to read the manifest files for attemp 0 and 1 as well.
> If there are multiple manifest files with the same name but different
> attemptId, Hive should only read the one with the biggest attempt Id.
