Neal Richardson created ARROW-8266: -------------------------------------- Summary: [C++] Add backup mirrors for external project source downloads Key: ARROW-8266 URL: https://issues.apache.org/jira/browse/ARROW-8266 Project: Apache Arrow Issue Type: Improvement Components: C++ Reporter: Neal Richardson Assignee: Neal Richardson Fix For: 0.17.0
As we've seen a number of times, most recently with boost, our builds sometimes fail because of a failure to download bundled dependencies. To reduce this risk, we can add alternate URLs to the cmake externalprojects, so that it will attempt to download from the second location if the first fails (https://cmake.org/cmake/help/latest/module/ExternalProject.html). This feature is available in cmake >=3.7. -- This message was sent by Atlassian Jira (v8.3.4#803005)
