Improve Close Index Response #39687

tlrx · 2019-03-05T10:01:08Z

This changes the CloseIndexResponse so that it reports closing result for each index. Shard failures or exception are also reported per index, and the global acknowledgment flag is computed from the index results only.

The response looks like:

{
  "acknowledged" : true,
  "shards_acknowledged" : true,
  "indices" : {
    "docs" : {
      "closed" : true
    }
  }
}

The response reports shard failures like:

{
  "acknowledged" : false,
  "shards_acknowledged" : false,
  "indices" : {
    "docs-1" : {
      "closed" : true
    },
    "docs-2" : {
      "closed" : false,
      "shards" : {
        "1" : {
          "failures" : [
            {
              "shard" : 1,
              "index" : "docs-2",
              "status" : "BAD_REQUEST",
              "reason" : {
                "type" : "index_closed_exception",
                "reason" : "closed",
                "index_uuid" : "JFmQwr_aSPiZbkAH_KEF7A",
                "index" : "docs-2"
              }
            }
          ]
        }
      }
    },
    "docs-3" : {
      "closed" : true
    }
  }
}

Looking good. Can @henningandersen give this a look as well? Thank you

henningandersen

Thanks @dnhatn , I left a few comments, my primary concern is the comment on handling when closeRoutingTable skips indices.

server/src/main/java/org/elasticsearch/action/admin/indices/close/CloseIndexResponse.java

henningandersen · 2019-04-30T10:16:48Z

server/src/main/java/org/elasticsearch/cluster/metadata/MetaDataIndexStateService.java

-                                                .map(result -> result.getKey().getName())
-                                                .filter(index -> newState.routingTable().hasIndex(index))
+                                            final List<IndexResult> indices = new ArrayList<>(results.values());
+                                            final boolean acknowledged = indices.stream().noneMatch(IndexResult::hasFailures);


In closeRoutingTable, we check for:

currentState.blocks().hasIndexBlock(index.getName(), closingBlock) == false

I think this will not be matched anymore by this acknowledged check, meaning acknowledged would be true afterwards?

Also, I would think that if the block was gone and the index thus is left open, we should see a failure for it in the response?

Good observation :). I pushed 434696b to report error if closing block disappeared.

@henningandersen I addressed your comments. Can you please give it another look? Thank you!

henningandersen

LGTM.

server/src/main/java/org/elasticsearch/action/admin/indices/close/CloseIndexResponse.java


 public class CloseIndexResponse extends ShardsAcknowledgedResponse {

+    private List<IndexResult> indices;
+
    CloseIndexResponse() {
    }

    public CloseIndexResponse(final boolean acknowledged, final boolean shardsAcknowledged) {


nit: maybe we should remove this constructor to ensure it is no longer used? I personally prefer to let the caller explicitly pass the empty list, but this may be personal preference so feel free to omit.

+1. I pushed 1c9ddf0.
