Shalin Shekhar Mangar commented on SOLR-9317:
---------------------------------------------
This turned out to be a bigger rabbit hole than I imagined. A lot of changes
were required.
# Add Replica API now supports nrtReplicas, pullReplicas, tlogReplicas,
createNodeSet parameters
# Create Shard API supports nrtReplicas, pullReplicas, tlogReplicas parameters
# Support for the new parameters have been added in corresponding SolrJ classes.
# CreateShardCmd delegates adding replicas entirely to Add Replica API
# CreateShardCmd cleans up slices from cluster state in case an
AssignmentException is thrown by the Add Replica API
# Refactorings were required in Add Replica API to break the huge monolithic
method into smaller ones e.g. finding replica positions, assigning and
validating core names and actual creation of cores are now separate methods
# Fixed a bug in
{{TestSimPolicyCloud.testCreateCollectionAddShardWithReplicaTypeUsingPolicy}}
which was using the same node as target for tlog and pull replicas.
# New test method in AddReplicaTest asserts creating multiple replicas together
There is still one failure in SplitShard API with rules that I trying to track
down. Rest all tests pass.
> ADDREPLICA command should be more flexible and add 'n' replicas to a
> collection,shard
