CloseableThriftHiveMetastoreIfaceClientFactory new instance get blocked

[chenwyi2]

recently, the waggle-dance is blocekd when inlitialize CloseableThriftHiveMetastoreIfaceClientFactory.java new instance, then the serve cannot be used. these is jstack

defaultMetaStoreClientFactory .newInstance(confFactory.newInstance(), "waggledance-" + name, DEFAULT_CLIENT_FACTORY_RECONNECTION_RETRY, connectionTimeout); why should use confFactory.newInstance() rather than use hiveConf in the paramter, becasue confFactory.newInstance() will synchronized(HiveConf.class), all the requets can be blocked there

Hey @chenwyi2, could you add more details of your use case? Which is the input configuration that you set in Waggledance? Does this occur when Waggledance is trying to map databases in parallel?

I didn't see this error before, and we are running multiple instances of Waggledance with different configurations. I would like to know what is different in your use case. Also I'm open to code suggestions :)
