Ryan Skraba commented on BEAM-5164:
-----------------------------------
I checked with a spark local run on Spark 2.4.3, there is no issue (expected,
since it includes the "right" parquet jars in the spark-supplied classpath).
The workaround that I proposed in the stack overflow question works for Spark
2.2, 2.3 and 2.4, but is only a workaround... I added the following relocations
to the "fat jar" build proposed in the Spark runner instructions:
```
<relocation>
<pattern>org.apache.parquet</pattern>
<shadedPattern>shaded.org.apache.parquet</shadedPattern>
</relocation>
<!-- Some packages are shaded already, and on the original spark
classpath. Shade them more. -->
<relocation>
<pattern>shaded.parquet</pattern>
<shadedPattern>reshaded.parquet</shadedPattern>
</relocation>
<relocation>
<pattern>org.apache.avro</pattern>
<shadedPattern>shaded.org.apache.avro</shadedPattern>
</relocation>
```
