Colin Patrick McCabe commented on SENTRY-1316:
----------------------------------------------
* Remove old MetastorePluginWithHA.java and UpdateForwarderWithHA.java code
* add curator dependency to {{sentry-provider/sentry-provider-common/pom.xml}}
* add
{{sentry-provider/sentry-provider-common/src/test/resources/log4j.properties}}
so that sentry-provider-common tests can use log4j and see test output
* add {{LeaderStatus}}, a class which encapsulates the logic needed to
determine active vs. standby. It handles both the HA and non-HA case.
* add {{LeaderStatusAdaptor.java}}, the glue code for interacting with Curator.
I used this rather than {{LeaderLatch}} since the latter was more complex and
required more code to use.
* {{SentryService.java}}: create a new {{LeaderStatus}} object when starting up.
* {{TestLeaderStatus.java}}: test the HA and non-HA cases.
