https://issues.apache.org/jira/browse/INFRA-15971
The 5.0.0-alpha rc0 crushed this limit with a whopping 410MB bin-tarball. INFRA temporarily increased this limit for me to commit the RC to the staging area, but I've asked them to increase our limit to 500MB.
This is probably a good time for us to try to trim some fat, e.g. the phoenix-pig jar is larger than the phoenix-client jar.
