DRILL-8200: Update Hadoop libs to ≥ 3.2.3 for CVE-2022-26612 (#2525)
* Remove pointless Buffer casts.
Compiling Drill with JDK > 8 will still result in ByteBuffer <-> Buffer cast
exceptions at runtime when running on JDK 8 even though maven.target.version
is set to 8. Setting maven.compiler.release to 8 solves the Buffer casts
but raises a compilation error of package sun.security.jgss does not exist
for JDK 8. There were a few handwritten casts to avoid the Buffer casting
issue but many instances are not covered so the few reverted in this commit
achieve nothing.
* Update Hadoop to 3.2.3.
