hello, want ask a question, kyuubi-hive-jdbc is only a driver engine, which cannot read configuration from the kyuubiConf, so if we set a strategy configEntry in HA, the kyuubi-hive-jdbc also cannot read the config, the only way i think is to add in connection params, but if add in connection params, we cannot custom our strategy, what do you think?

@davidyuan1223 hello, May I ask what strategy will you implement?

@davidyuan1223 hello, May I ask what strategy will you implement?

sorry, forget response, curruntly, i implemented poll and random, because hive-jdbc module is a single module, we can not use kyuubi-ha module, so, if we want implemented more strategies, we only can add strategy in connection params, like '&zkStartegy=poll/random', if you have more useful starategy, you can give me some advice

@davidyuan1223 hello, May I ask what strategy will you implement?

hello, this is the demo command
bin/beeline -u 'jdbc:hive2://xxx:2181/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=kyuubi;zooKeeperStrategy=poll?spark.app.name=testspark;spark.shuffle.useOldFetchProtocol=true' -n hadoop --verbose=true --showNestedErrs=true
currently it can use poll strategy to choose the right server, but there are some bugs, so i'm not commit a pr.

i plan the user could implemented a interface named org.apache.kyuubi.jdbc.hive.strategy.ChooseServerStrategy, then use zooKeeperStrategy=xxx.xxx.xxx, so user can use themselves implement plan, of course, if you have more effective plan, you can offered me, and i will try to implement them
