[SPARK-12807] [YARN] [WIP] Spark External Shuffle not working in Hadoop
clusters with Jackson 2.2.3
Patch to
1. Shade jackson 2.x in spark-yarn-shuffle JAR
2. Use maven failsafe integration test to verify the JAR has the renamed
classes
The initial patch doesn't have feature (1) working yet, even though the
code matches what we shade elsewhere. Hence the WIP attribute
