Hi:
after install the ambari version 2.2.1.0 same like ambari server and execute
ambari-agent start
now is working well
then I registered MANUALLYthe host, the warning are because there are some directories that i need to remove,,but is ok
[root@xxxxhdp]# python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py --silent --skip=users
after Rerun check ()the blue botton, everything is fine.
and now all nodes are working
{ "href" : "http://xxxxx:8080/api/v1/hosts", "items" : [ { "href" : "http://xxxxxx:8080/api/v1/hosts/a01hop04", "Hosts" : { "host_name" : "a01hop04" } }, { "href" : "http://xxxxx:8080/api/v1/hosts/a01hop01", "Hosts" : { "cluster_name" : "RSI_DE", "host_name" : "a01hop01" } }, { "href" : "http://xxxx:8080/api/v1/hosts/a01hop02", "Hosts" : { "cluster_name" : "RSI_DE", "host_name" : "a01hop02" } }, { "href" : "http://xxxx:8080/api/v1/hosts/a01hop03", "Hosts" : { "cluster_name" : "RSI_DE", "host_name" : "a01hop03" } } ] }
