PJ Fanning commented on PIG-5464:
---------------------------------
The internal Pig code should be able to use whatever Jackson version you like.
If an old version of Hadoop needs Jackson 1, then the package names are
different so the Jackson 1 and 2 jars won't clash.
> Move off from jackson-mapper-asl and jackson-core-asl

> Similar to HADOOP-15983 and SPARK-30466, we need to move off from
> jackson-mapper-asl-1.9.13 and jackson-core-asl-1.9.13.
> However, this is only possible for Hadoop3.
