------------------------------------

             Summary: HBase service components should indicate security state
                 Key: AMBARI-8482
                 URL: https://issues.apache.org/jira/browse/AMBARI-8482
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server, stacks
    Affects Versions: 2.0.0
            Reporter: Robert Levas
            Assignee: Robert Levas
             Fix For: 2.0.0


The HBase service components should indicate security state when queried by Ambari Agent via STATUS_COMMAND.  Each component should determine it's state as follows:

h3. HBASE_MASTER
h4. Indicators
* Command JSON
** config\['configurations']\['cluster-env']\['security_enabled'] 
*** = “true”
* Configuration File: params.hbase_conf_dir + ‘hbase-site.xml’
** hbase.security.authentication
*** = “kerberos”
*** required
** hbase.security.authorization
*** = “true”
*** required
** hbase.master.keytab.file
*** not empty
*** path exists and is readable
*** required
** hbase.master.kerberos.principal
*** not empty
*** required

h4. Pseudocode
{code}
if indicators imply security is on and validate
    if kinit(hbase master principal) succeeds
        state = SECURED_KERBEROS
    else
        state = ERROR 
else
    state = UNSECURED
{code}

h3. HBASE_REGIONSERVER
h4. Indicators
* Command JSON
** config\['configurations']\['cluster-env']\['security_enabled'] 
*** = “true”
* Configuration File: params.hbase_conf_dir + ‘hbase-site.xml’
** hbase.security.authentication
*** = “kerberos”
*** required
** hbase.security.authorization
*** = “true”
*** required
** hbase.regionserver.keytab.file
*** not empty
*** path exists and is readable
*** required
** hbase.regionserver.kerberos.principal
*** not empty
*** required

h4. Pseudocode
{code}
if indicators imply security is on and validate
    if kinit(hbase region server principal) succeeds
        state = SECURED_KERBEROS
    else
        state = ERROR 
else
    state = UNSECURED
{code}

h3. HBASE_CLIENT
h4. Indicators
* Command JSON
** config\['configurations']\['cluster-env']\['security_enabled'] 
*** = “true”
* Configuration File: params.hbase_conf_dir + ‘hbase-site.xml’
** hbase.security.authentication
*** = “kerberos”
*** required
** hbase.thrift.keytab.file
*** not empty
*** path exists and is readable
*** required, if _rest_ credentials are not set
** hbase.thrift.kerberos.principal
*** not empty
*** required, if _rest_ credentials are not set
** hbase.rest.keytab.file
*** not empty
*** path exists and is readable
*** required, if _thrift_ credentials are not set
** hbase.rest.kerberos.principal
*** not empty
*** required, if _thrift_ credentials are not set

h4. Pseudocode
{code}
if indicators imply security is on and validate
    if kinit(hbase rest|thrift principal) succeeds
        state = SECURED_KERBEROS
    else
        state = ERROR 
else
    state = UNSECURED
{code}

_*Note*_: Due to the _cost_ of calling {{kinit}} results should be cached for a period of time before retrying.  This may be an issue depending on the frequency of the heartbeat timeout.

_*Note*_: There may be additional work related to _REST gateway impersonation_
