>             Project: Spark
>          Issue Type: Bug
>          Components: SQL

> Original problem is 
> [SPARK-3764|https://issues.apache.org/jira/browse/SPARK-3764].
> {{AppendingParquetOutputFormat}} uses a binary-incompatible method 
> {{context.getTaskAttemptID}}.
> This causes binary-incompatible of Spark itself, i.e. if Spark itself is 
> built against hadoop-1, the artifact is for only hadoop-1, and vice versa.
