Junping Du commented on HDFS-11431:
-----------------------------------
bq. Why not try and fix it properly for 2.9?
+1 on fixing it more properly for 2.9. However, we shouldn't be risky if the
missing class are not moved by then or other classes are found missing. I
checked the code with some HDFS guy it seems ConfiguredFailoverProxyProvider is
not very clean to move as include some server side logic. So, I think keeping
this patch on branch-2 is benign which is a different case for trunk where
build will be broken by the patch.
bq. I think it also makes the tracking easier, since otherwise the fix versions
don't reflect where the code is.
I don't understand your point. In our current practice, all 2.8.x patches
should be in branch-2 first. I think that's easier for track.
bq. The current fix thus falls in the "hack" category, and I'd rather we not
default to carrying it forward to future bramch-2 releases.
If we have elegant fixes, I am OK with get fixes in. Otherwise, HDFS-6200
doesn't achieve its goal. However, I would rather exclude one feature which
could cause regression rather than stopping the whole branch-2 release trains.
In this sense, the patch here is still benign for branch-2.
