2888 and 3888 are the internal ports for zookeeper nodes. you need 2888 and 3888 for intra connectivities between zookeeper nodes. 2181 is the client port for zookeeper cluster. so you don’t need 2181 between zookeeper nodes. however 2181 is need to be accessible from broker/bookie nodes. ---- 2018-08-23 12:26:58 UTC - Ganga Lakshmanasamy: @Ganga Lakshmanasamy has joined the channel ---- 2018-08-24 08:46:54 UTC - Denis: @Denis has joined the channel ----
