Thank you for the RC, Steve.
* Verified all checksums.
* Verified all signatures.
* Built from source, including native code on Linux.
* mvn clean package -Pnative -Psrc -Drequire.openssl -Drequire.snappy
-Drequire.zstd -DskipTests
* Tests passed.
* mvn --fail-never clean test -Pnative -Dparallel-tests
-Drequire.snappy -Drequire.zstd -Drequire.openssl
-Dsurefire.rerunFailingTestsCount=3 -DtestsThreadCount=8
* For ARM verification:
* Ran "file <X>" on all native binaries in the ARM tarball to confirm
they actually came out with ARM as the architecture.
* Output of hadoop checknative -a on ARM looks good.
* Ran a MapReduce job with the native bzip2 codec for compression, and
it worked fine.
