We are seeing horrible problems. We cannot move data through our 0.8 borker because we are getting socket timeout exceptions and I cannot figure out what settings should be. The fetch metadata stuff is throwing these exceptions and no matter how I tweak the timeouts, I still get horrible timeouts and no progress on moving data.
On test environments where there are only 12 topics there are no problems. When the number of topics goes to ~75, then we can't move anything because the fetch metadata requests time out. What can we do to fix this????????? I am desperate.
