Instead of terminating with an uncaught exception the benchmark runner now logs that there was an error.
In addition, we add a new syntax
retry load N
which can be used to retry the load phase up toN
times in case of errors. We use this in the h2oai benchmark (which downloads CSV files from a remote source and sporadically runs into failures on our CI).
