Shixiong Zhu updated SPARK-19721:
---------------------------------
Fix Version/s: 2.2.0
> Good error message for version mismatch in log files
> ----------------------------------------------------
>
> Key: SPARK-19721
> URL: https://issues.apache.org/jira/browse/SPARK-19721
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 2.1.0
> Reporter: Michael Armbrust
> Priority: Blocker
> Fix For: 2.2.0
>
>
> There are several places where we write out version identifiers in various
> logs for structured streaming (usually {{v1}}). However, in the places where
> we check for this, we throw a confusing error message. Instead, we should do
> the following:
> - Find all of the places where we do this kind of check.
> - for {{vN}} where {{n>1}} say "UnsupportedLogFormat: The file {{path}} was
> produced by a newer version of Spark and cannot be read by this version.
> Please upgrade"
> - for anything else throw an error saying the file is malformed.
