@Hoang Le The command "/usr/hdp/current/zookeeper-client/bin/zookeeper-client" should work becase it is able to locate the zookeeper conf directory as following: # cat /usr/hdp/current/zookeeper-client/bin/zookeeper-client #!/bin/bash export ZOOKEEPER_HOME=/usr/hdp/2.5.0.0-1245//zookeeper export ZOOKEEPER_CONF=${ZOOKEEPER_HOME}/conf export CLASSPATH=$CLASSPATH:$ZOOKEEPER_CONF:$ZOOKEEPER_HOME/*:$ZOOKEEPER_HOME/lib/* export ZOOCFGDIR=${ZOOCFGDIR:-$ZOOKEEPER_CONF} env CLASSPATH=$CLASSPATH ${ZOOKEEPER_HOME}/bin/zkCli.sh "$@" .
