}


Groups created

vcp-9999-hdfs:x:16031:vcp-9999-hdfs
vcp-9999-hadoop:x:16032:vcp-9999-zookeeper,vcp-9999-hbase,vcp-9999-kafka,vcp-9999-ams,vcp-9999-hdfs
zookeeper:x:498:
hadoop:x:497:
yarn:x:496:

hdfs:x:494:

Users created
vcp-9999-zookeeper:x:16028:16032::/home/vcp-9999-zookeeper:/bin/bash
vcp-9999-hbase:x:16031:16032::/home/vcp-9999-hbase:/bin/bash
vcp-9999-ambari-qa:x:16034:16032::/home/vcp-9999-ambari-qa:/bin/bash

kafka:x:995:492:KAFKA:/home/kafka:/bin/bash

Can any one help to explain that why groups and users created ( in bold text) even though I have added properties.

How can we remove these users at the time of creation.

Thanks!
