Hi everyone,
Since there is no hedwig API to delete a topic, I used zookeeper java client to delete the znodes associated with that topic. For an example, I delete /hedwig/standalone/topics/mytopic and its child znode(s) in order to delete a topic named, "mytopic". As a result, bookies would delete data associated with this topic as well. However, I can still publish and subscribe to "mytopic" topic at this point even though there is no znodes or data for this topic. The hub kept all the cache and believes that the topic is still "alive". The documents says that the hub will lose its topic ownership if the hub is overloaded or the periodic redistribution kicks in. Is there any way to tell the hub to forget about the topic? Regard, Daniel S. Kim
