[jira] [Created] (AMBARI-9037) Storm service components should
indicate security state
Robert Levas created AMBARI-9037:
------------------------------------
Summary: Storm service components should indicate security state
Key: AMBARI-9037
URL: https://issues.apache.org/jira/browse/AMBARI-9037
Project: Ambari
Issue Type: Task
Components: ambari-server, stacks
Affects Versions: 2.0.0
Reporter: Robert Levas
Assignee: Robert Levas
Fix For: 2.0.0
The Storm service components should indicate security state when queried by Ambari Agent via STATUS_COMMAND. Each component should determine it's state as follows:
h3. DRPC_SERVER
h4. Indicators
* Command JSON
** config\['configurations']\['cluster-env']\['security_enabled']
*** = “true”
* Configuration File: params.conf_dir + ‘/storm-jaas.conf’
** StormServer/keyTab
*** not empty
*** path exists and is readable
*** required
** StormServer/principal
*** not empty
*** required
h4. Pseudocode
{code}
if indicators imply security is on and validate
if kinit(drpc server master principal) succeeds
state = SECURED_KERBEROS
else
state = ERROR
else
state = UNSECURED
{code}
h3. STORM_UI_SERVER
h4. Indicators
* Command JSON
** config\['configurations']\['cluster-env']\['security_enabled']
*** = “true”
* Configuration File: params.conf_dir + ‘/storm-jaas.conf’
** StormClient/keyTab
*** not empty
*** path exists and is readable
*** required
** StormClient/principal
*** not empty
*** required
h4. Pseudocode
{code}
if indicators imply security is on and validate
if kinit(storm ui server principal) succeeds
state = SECURED_KERBEROS
else
state = ERROR
else
state = UNSECURED
{code}
h3. NIMBUS
h4. Indicators
* Command JSON
** config\['configurations']\['cluster-env']\['security_enabled']
*** = “true”
* Configuration File: params.conf_dir + ‘/storm-jaas.conf’
** StormServer/keyTab
*** not empty
*** path exists and is readable
*** required
** StormServer/principal
*** not empty
*** required
h4. Pseudocode
{code}
if indicators imply security is on and validate
if kinit(nimbus master 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*_: {{kinit}} calls should specify a _temporary_ cache file which should be destroyed after command is executed - BUG-29477
_*Note*_: There may be additional work related to _REST gateway impersonation_
