Maximilian Michels commented on BEAM-6418:
------------------------------------------
The Jenkins test environment is very memory constraint. We get killed by the
host OS (exit code 137) while running tests for two FlinkRunner versions
(1.5/1.6) in parallel. Initially, this problem became visible after adding the
1.7 target, but it looks like the general memory load of the tests has
increased. Thus, I will also disable test execution for 1.6.
Generally speaking, it seems to be a Jenkins problem because the test JVM can't
acquire the max memory that it has been provided (currently set to max 4GB per
parallel instance) without getting killed by the host OS.
