Like in this build: https://travis-ci.org/apache/flink/builds/600325708
We’ve already upload the cache master/cache-linux-xenial-433d76a3a6c0ab0da54540cd752c32ebf9a0b09c67a9e8ffc5990eef344886ff–jdk-openjdk8.tgz during the compile stage, and some of the testing stages can also download the cache successfully, except for tests and misc stage.
Any idea why this happened and how to ease this issue?
