Thanks Erick for a quick response. Here are my responses for your questions 1# I did make sure that zoo.cfg got the proper data dir and its not pointing to temp folder; do I need to set the variables in ZK_ENV.sh. as well on top of the zoo.cfg ??
2# I can confirm that we are not using the embedded one but we are using a standalone zookeeper 3.4.14 and also the admin UI is showing what we configured (port 2181) Here are my confusions, as I said we are in two node architecture in DEV but maintaining only one instance of zookeeper, is that true that I need to maintain the same folder structure that we specify on the dataDir of zoo.cfg on both the nodes ??
