[15/50] [abbrv] helix git commit: Ignore instances with no instance
configuration
Posted by jx...@apache.org.
Ignore instances with no instance configuration
Ignore instances with no instance configuration when fetching the list
of instances that have a specific tag.
The deletion order in ZKHelixAdmin#dropInstance deletes the instance
configuration before deleting the instance itself. If this is
interrupted midway, the instance configuration is deleted but the
instance is present in the list of instances.
When fetching the list of instances with a given tag, this means that
if an instance has its configuration missing, the instance
configuration will be null and the loop will exit with NPE. This patch
adds a null check to avoid aborting the loop.

[36/50] [abbrv] helix git commit: Make map in NotificationContext
synchronized
Posted by jx...@apache.org.
Make map in NotificationContext synchronized
One issue we observed is that when batch messages enabled, it will have NPE in ZNRecord merge record.
Race condition could be the root cause. The only place can have race condition is the current state update map in NotificationContext, which is passed as input for multiple sub tasks in BatchMessageHandler.

Posted by jx...@apache.org.
[HELIX-653] Fix enable/disable partition in instances for resource specific

[41/50] [abbrv] helix git commit: Fix TestClusterVerifier
Posted by jx...@apache.org.
Fix TestClusterVerifier
Full-Auto verifier requires BestPossibleState to be persisted but this
change hasn’t been synced into the code base from LinkedIn Helix yet.
Patch an ad-hoc fix for TestClusterVerifier, in order to publish new
release quickly. This verifier will be synced with LinkedIn Helix later.

[46/50] [abbrv] helix git commit: [HELIX-657] Fix unexpected
idealstate overwrite when persist assignment is on.
Posted by jx...@apache.org.
[HELIX-657] Fix unexpected idealstate overwrite when persist assignment is on.
1. Change persist method from set to update in PersistAssignmentStage.
The new updater only overwrites map and list fields that the controller will update during PersistAssignmentStage.
All the other updates from other sources that are made during controller read and write will be kept, as long as those fields are not purposely updated by the controller.
If current node does not exist, new updater return null.
2. Update accessors who relies on updater to check new data before applying the change. If the returned new data is null, should skip updating or creating.
Also, add a test case for PersistAssignmentStage to cover the change.

AutoRebalanceStrategy replica not assigned
Posted by jx...@apache.org.
[HELIX-631] Fix AutoRebalanceStrategy replica not assigned
In our current AutoRebalanceStrategy, Helix uses greedy algorithm to assign replicas. With the constraint that two replicas from same partition should not assigned to same node and nodes' capacity calculated by evenly distributed. Thus there may some replicas are not assigned.
With this fix, Helix will try to force assign the orphaned replicas to the node with minimum overload. This may cause imbalanced assignment.

[16/50] [abbrv] helix git commit: Test base refactoring and add new
synchronize tests
Posted by jx...@apache.org.
Test base refactoring and add new synchronize tests
Due to heavy asynchronized tests running in Helix, current tests are running slow. Thus introduce these new synchronized tests to improve the test efficiency.
1. Split out TaskSynchronizedTestBase.
2. Add synchronized test for delay jobs.

[26/50] [abbrv] helix git commit: Make more user friendly API change
Posted by jx...@apache.org.
Make more user friendly API change
Current API provide a map that returns resource to disabled partitions that combined in one String. Change to return a map that returns resource to list of disabled partitions.

[14/50] [abbrv] helix git commit: Support cancel tasks with
synchronized check task status
Posted by jx...@apache.org.
Support cancel tasks with synchronized check task status
Currently, in Helix, cancel and stop a job does not check subtasks status. In this rb:
1. Add new API to support sync stopping a workflow/queue
2. Controller side check subtasks are stopped before mark job status.
