Please try this.

Step1). On the ambari server host run the following command:

# /var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin -port 8080 get amb25101.example.com plain_ambari cluster-env  /tmp/cluster-env.txt

You should see the file "/tmp/cluster-env.txt" content something like following, NOTICE the "recovery_enabled" is set to "false" (that you need to make as "true")

"properties" : {
"agent_mounts_ignore_list" : "",
"alerts_repeat_tolerance" : "1",
"enable_external_ranger" : "false",
"fetch_nonlocal_groups" : "true",
"hide_yarn_memory_widget" : "false",
"ignore_bad_mounts" : "false",
"ignore_groupsusers_create" : "false",
"kerberos_domain" : "EXAMPLE.COM",
"manage_dirs_on_root" : "true",
"managed_hdfs_resource_property_names" : "",
"one_dir_per_partition" : "false",
"override_uid" : "true",
"recovery_enabled" : "false",
.
.
.

Step2). Now edit the file "/tmp/cluster-env.txt" and set the "recovery_enabled" : "true".

Step3). Now run the same config.sh command but this time instead of "get" use "set" to set the "recovery_enabled" is set to "true".

# /var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin -port 8080 set amb25101.example.com plain_ambari cluster-env  /tmp/cluster-env.txt

Step4). refresh the ambari ui and check again the "Auto Recobery Page"

Please Change the Following values in the config.sh command

Here in the above command please replace the ambari admin credentials
"amb25101.example.com" replace with your Ambari Server Hostname
"plain_ambari" with your ambari Cluster name.

That error you will get only when you have not specified the "Cluster Name" aftaer the ambari server hostname in the config.sh command:

/var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin -port 8080 get amb25101.example.com plain_ambari cluster-env /tmp/cluster-env.txt
