No in progress sequence of kind for (only in progress)

Error message

No in progress sequence of kind  for  (only  in progress)

What it means

After finding an in-progress sequence for the node, cancelInProgressSequences checks that its kind matches the requested kind (e.g. BOOTSTRAP vs REPLACE). A mismatch throws IllegalArgumentException naming the expected kind, the owner, and the kind actually in progress. It prevents cancelling a different operation than the operator intended.

Solutions

1. Read the actual in-progress kind from the error message and re-issue the cancel with that kind
2. Confirm what operation the node is performing (bootstrap vs replace vs other MultiStepOperation) before cancelling
3. Fix the automation/config that hard-codes the wrong kind
4. If both operations seem in flight, inspect TCM metadata; only one sequence per node should exist

Example fix

// before
seq.cancelInProgressSequences(owner, "BOOTSTRAP");
// after
MultiStepOperation<?> op = ClusterMetadata.current().inProgressSequences.get(NodeId.fromString(owner));
seq.cancelInProgressSequences(owner, op == null ? "BOOTSTRAP" : op.kind().name());

MultiStepOperation<?> op = ClusterMetadata.current().inProgressSequences.get(NodeId.fromString(owner));
if (op != null && !op.kind().name().equals(expectedKind))
    expectedKind = op.kind().name(); // align with actual

boolean kindMatches(String owner, String kind) {
    MultiStepOperation<?> op = ClusterMetadata.current().inProgressSequences.get(NodeId.fromString(owner));
    return op != null && op.kind() == MultiStepOperation.Kind.valueOf(kind);
}

try { cancelInProgressSequences(owner, kind); } catch (IllegalArgumentException e) { logger.warn("Kind mismatch: {}", e.getMessage()); }

When it happens

Trigger: Calling cancelInProgressSequences(owner, "BOOTSTRAP") while the node's in-progress sequence is of kind REPLACE (or vice versa); passing a kind string that is valid but not the one actually running.

Common situations: Copy-pasted nodetool/admin command with the wrong sequence kind; operator assumed a replace but the node is doing a bootstrap; automation using a stale kind after the operation was restarted as a different sequence.

Understand the failure class

Background: Invalid enum value errors: "Unknown type", "Invalid scope", "must be one of" — when a string is not on the library's allowed list — this error's family across 23 libraries.
