On all hosts, clean the yum repository.
yum clean all

Remove your old HDP 2.1 components. This command uninstalls the HDP 2.1 components. It leaves the user data, and metadata, but removes your configurations:

yum erase "hadoop*" "webhcat*" "oozie*" "collectd*" "gccxml*" "pig*" "hdfs*" "sqoop*" "zookeeper*" "hbase*" "hive*" "tez*" "storm*" "falcon*" "flume*" "phoenix*" "accumulo*" "mahout*" "hue" "hue-common" "hue-shell" "knox*" "hdp_mon_nagios_addons"

Validate that all HDP 2.1 component binaries are uninstalled:
yum list installed | grep @HDP2.1
Remove your old hdp.repo file:
rm /etc/yum.repos.d/hdp.repo

Install the HDP-2.5.5 repo:

Download the hdp.repo file:

wget -nv http://public-repo-1.hortonworks.com/HDP/centos<version>/2.x/updates/2.5.5.0/hdp.repo -O /etc/yum.repos.d/hdp.repo

Confirm the HDP repository is configured.
