> Thanx @abstractdog for the details. I think maybe the problem is we are
forcing the scope to test in `dependencyManagement` of the parent pom. I
believe if you just remove the scope from the parent pom, that should do. The
other modules can have it in test scope.

in Tez it is 1.78. Maybe we should keep them in sync.

[HADOOP-19024](https://issues.apache.org/jira/browse/HADOOP-19024), which was
introduced in Hadoop 3.4.1. Previously, Hadoop depended on `bcprov-jdk15on`,
whereas Tez declared `bcprov-jdk18on` in its dependencyManagement. Since Tez
did not explicitly declare `bcprov-jdk15on`, it was being pulled transitively
from Hadoop with its default (compile) scope, so it ended up being packaged
correctly.

> However, after
[HADOOP-19024](https://issues.apache.org/jira/browse/HADOOP-19024), Hadoop
itself now declares `bcprov-jdk18on`, which conflicts with Tez’s declaration
that forces its scope to test. As a result, the dependency is omitted from the
final package.
thanks @ayushtkn , absolutely makes sense
what's weird is that upstream tez, the fix works also without the version
harmonization, so only changing the root pom.xml
however, I need to consider 2 things:
1. version harmonization makes sense, I'll most probably add it
2. this fix doesn't work downstream, only if I change the tez-api pom.xml
too...I need to understand the difference before proceeding here
I'll keep you posted
