Impala 4 decided to drop Sentry support in favor of Ranger. This
removes Sentry support and related tests. It retires startup
flags related to Sentry and does the first round of removing
obsolete code. This does not adjust documentation to remove
references to Sentry, and other dead code will be removed
separately.
Some issues came up when implementing this. Here is a summary
of how this patch resolves them:
1. authorization_provider currently defaults to "sentry", but
"ranger" requires extra parameters to be set. This changes the
default value of authorization_provider to "", which translates
internally to the noop policy that does no authorization.
2. These flags are Sentry specific and are now retired:
- authorization_policy_provider_class
- sentry_catalog_polling_frequency_s
- sentry_config
3. The authorization_factory_class may be obsolete now that
there is only one authorization policy, but this leaves it
in place.
4. Sentry is the last component using CDH_COMPONENTS_HOME, so
that is removed. There are still Maven dependencies coming
from the CDH_BUILD_NUMBER repository, so that is not removed.
5. To make the transition easier, testdata/bin/kill-sentry-service.sh
is not removed and it is still called from testdata/bin/kill-all.sh.
Testing:
- Core job passes
