IMPALA-13920: Allow running minicluster with Java 17
IMPALA-11941 allowed building Impala and running tests with Java 17,
but it still uses Java 8 for minicluster components (e.g. Hadoop) and
skips several tests that would restart Hive. It should be possible to
use 17 for everything to be able to deprecate Java 8.
This patch mainly fixes Yarn+Hive+Tez startup issues with java 17 by
setting JAVA_TOOL_OPTIONS.
Another issues fixed is KuduHMSIntegrationTest: this test fails to
restart Kudu due to a bug in OpenJDK (see IMPALA-13856). The current
fix is to remove LD_PRELOAD to avoid loading libjsig (similarly to
the case when MINICLUSTER_JAVA_HOME is set). This works, but it
would be nice to clean up this area in a future patch.
Testing:
- ran exhaustive tests with Java 17
- ran core tests with default Java 8
