[4/4] sentry git commit: SENTRY-1317: Implement fencing required for
active/standby (Colin P. McCabe ,
Reviewed by: Hao Hao and Sravya Tirukkovalur)
Posted by sr...@apache.org.
SENTRY-1317: Implement fencing required for active/standby (Colin P. McCabe , Reviewed by: Hao Hao and Sravya Tirukkovalur)
New fencing and active/passive code
- Activator to store the state about whether the daemon is active or not, as well as manage fencing
- Create Fencer to implement SQL fencing.
- Add SqlAccessor to talk directly to SQL databases
LeaderStatus: generate shorter incarnation IDs by using base64.
LeaderStatusAdaptor: implement close()
Remove old code which is no longer used
- HAContext
- PluginCacheSyncUtil
- TestHAUpdateForwarder
- ServiceRegister
SentryStore
- move DataNucleus properties setup into a utility function
- Remove unused DEFAULT_DATA_DIR variable (it's not used anywhere in the code)
- SentryStore should maintain a reference to the Activator
Add SentryStandbyException to indicate that the daemon is currently standby
Move SENTRY_ZK_JAAS_NAME from HAContext to SentryConstants
DelegateSentryStore: make some fields final

+ * users start up multiple non-HA sentry daemons, only one can become
+ * active.<p/>
+ *
+ * The fencer uses a special SQL table, the SENTRY_FENCE table. When a sentry
+ * process becomes active, it renames this table so that the name contains the
+ * current "incarnation ID." The incarnation ID is a randomly generated 128-bit
+ * ID, which changes each time the process is restarted. From that point
+ * forward, the sentry process includes a SELECT query for the SENTRY_FENCE
+ * table in all update transactions. This ensures that if the SENTRY_FENCE
+ * table is subsequently renamed again, those update transactions will not
+ * succeed.<p/>
+ *
+ * It is important to distinguish between fencing and leader election.
+ * ZooKeeper is responsible for leader election and ensures that there is only
+ * ever one active sentry daemon at any one time. However, sentry exists in an
+ * asynchronous network where requests from a previously active daemon may be
+ * arbitrarily delayed before reaching the SQL databse. There is also a delay
+ * between a process being "de-leadered" by ZooKeeper, and the process itself
+ * becoming aware of this situation. Java's garbage collection pauses tend to
+ * expose these kinds of race conditions. The SQL database must be prepared to
+ * reject these stale updates.<p/>
+ *
+ * Given that we need this SQL fencing, why bother with ZooKeeper at all?
+ * ZooKeeper detects when nodes have stopped responding, and elects a new
+ * leader. The SQL fencing code cannot do that.<p/>

[2/4] sentry git commit: SENTRY-1329: Adapt
SentryMetaStorePostEventListener to write HMS notification logs
Posted by sr...@apache.org.
SENTRY-1329: Adapt SentryMetaStorePostEventListener to write HMS notification logs
Also,
1. Implementing the SentryJSONMessageFactory to add custom information in the notification log entry message, which includes
1.1. Implementing Message class for each message type
1.2. Implementing a deserializer
2. Implementing JSONAlterPartitionMessage and JSONAlterTableMessage to work around the issue in Hive 1.1.0. These classes do not have required default constructor.
3. Testing:
3.1. Sentry functionality: TestSentryListenerSentryDeserializer to verify functionality using Sentry's SentryMetastorePostEventListener and Sentry Notification log deserializer.
3.2. TestDbNotificationListenerSentryDeserializer uses Hive's DbNotificationListener and Sentry's JSON deserializeri. This would make sure Sentry is able to read the Notification logs written by Hive's DBNotificationListener
3.3. TestSentryListenerInBuiltDeserializer uses Sentry's SentryMetastorePostEventListener and Hive's inbuilt Notification log deserializer: This would make sure Sentry is not breaking other users of NotificationLog who might be using Hive's in built serializer

+A HMS listener class which should ideally go into the transaction which persists the Hive metadata.
+This class writes all DDL events to the NotificationLog through rawstore.addNotificationEvent(event)
+This class is very similar to DbNotificationListener, except:
+1. It uses a custom SentryJSONMessageFactory which adds additional information to the message part of the event
+ to avoid another round trip from the clients
+2. It handles the cases where actual operation has failed, and hence skips writing to the notification log.
+3. Has additional validations to make sure event has the required information.
+
+This can be replaced with DbNotificationListener in future and sentry's message factory can be plugged in if:
+- HIVE-14011 is fixed: Make MessageFactory truly pluggable
+- 2 and 3 above are handled in DbNotificationListener
