-----------------------------------
Summary: E2E tar ball cache fails without error message if target
directory not specified
Key: FLINK-25041
URL: https://issues.apache.org/jira/browse/FLINK-25041
Project: Flink
Issue Type: Bug
Components: Test Infrastructure
Affects Versions: 1.13.3, 1.14.0, 1.15.0
Reporter: Fabian Paul
We want to verify if the variable has been set.
{code:java}
if [ -z "$E2E_TARBALL_CACHE" ] ; then
echo "You have to export the E2E Tarball Cache as E2E_TARBALL_CACHE"
exit 1
fi {code}
but the shown code immediately fails with an `unbound variable` error if the
variable is not set and it does not evaluate the branch.
We should change it to something like this
{code:java}
if [ "${E2E_TARBALL_CACHE+x}" == x ] ; then
echo "You have to export the E2E Tarball Cache as E2E_TARBALL_CACHE"
exit 1
fi {code}
