Reply To: Ambari 2.0 rolling upgrades

Thank you Alejandro for this very complete answer.

I checked by a request on http://server:8080/api/v1/clusters/c1/stack_versions/1 and I’m getting this result :

{
"href" : "http://server:8080/api/v1/clusters/HDP_TEST/stack_versions/1",
"ClusterStackVersions" : {
"cluster_name" : "HDP_TEST",
"id" : 1,
"repository_version" : 1,
"stack" : "HDP",
"state" : "UPGRADING",
"version" : "2.2",
"host_states" : {
"CURRENT" : [
"SLAVE5",
"SLAVE4",
"SLAVE3",
"SLAVE2"
],
"INSTALLED" : [ ],

"INSTALL_FAILED" : [ ],
"OUT_OF_SYNC" : [ ],
"UPGRADED" : [ ],
"UPGRADE_FAILED" : [ ],
"UPGRADING" : [

}
},
"repository_versions" : [
{
"href" : "http://server:8080/api/v1/clusters/HDP_TEST/stack_versions/1/repository_versions/1",
"RepositoryVersions" : {

"stack_version" : "2.2"
}
}
]
}


Before going further, what is the DB you are querying in point 1 ?

Thank you.
