huijunw commented on issue #2907: stuck stmgr due to zk client destructor URL: https://github.com/apache/incubator-heron/issues/2907#issuecomment-391546584 @srkukarni why is zookeeper not single thread ? libzookeeper_mt vs libzookeeper_st If I remember correctly, the stmgr should be single thread and the zkclient should be in the same main thread. What we observed is that zk client is multi thread. I would like to know if this is intended, and shall we make zk client share the same single main thread
