Bryan Beaudreault commented on HDFS-15910:
------------------------------------------
FYI, this breaks the ability to build hadoop 3.3 on Centos 6. I realize the
BUILDING docs only give guidance for Centos 8, but prior to this I was able to
build hadoop with Centos 6. The fix HDFS-15977 has not been backported to
branch-3.3, so this remains broken for 3.3 for now.
> Replace bzero with explicit_bzero for better safety
