László Bodor updated TEZ-4157:
------------------------------
Description:
-In the dependency tree, there are 2 occurrences of compile scope direct netty
dependencies, however, they're not used at all. I compiled locally successfully
without them.
E.g. when investigating blackduck alerts (complaining about netty deps for
current 3.10.5.Final), it would be cleaner to start from a dependency tree
where Tez doesn't depend on netty directly in order to eliminate its
responsibility (and move the focus to underlying hadoop for instance).
-
Tez depends on netty3 almost only in ShuffleHandler and some related classes.
We can eliminate netty3 by upgrading it, but this effort might involve some
testing due to fundamental [changes from
netty3->netty4|https://netty.io/wiki/new-and-noteworthy-in-4.0.html].
