No drop table operation is in progress for table with id

Error message

No drop table operation is in progress for table with id

What it means

Thrown (as IllegalArgumentException) by CMSOperations.resumeDropAccordTable when no in-progress drop-table transformation exists for the given table id. Resume only works for Accord table drops that were started and interrupted; the in-progress sequence key must still be registered.

Solutions

Verify the table id is correct and that a drop operation is actually in progress.
If the drop already completed, no resume is needed - the table is gone.
Re-initiate a new drop operation if none is in progress.

Example fix

// before
CMSOperations.instance().resumeDropAccordTable(staleTableId);
// after
if (isDropInProgress(tableId)) CMSOperations.instance().resumeDropAccordTable(tableId);

Defensive patterns

Strategy: validation

Validate before calling

if (!dropInProgress(tableId)) { /* no resume needed */ return; }

Try / catch

try { ops.resumeDropAccordTable(tableId); } catch (IllegalArgumentException e) { logger.warn("No drop in progress for {}: {}", tableId, e.getMessage()); }

Prevention

Track in-progress drops keyed by table id
Confirm the drop actually started before resuming
Handle already-completed drops as no-ops

When it happens

Trigger: Calling resumeDropAccordTable(TableId) for a table whose drop either never started, already completed (sequence finished), or whose id does not match any DropAccordTable.TableReference in progress.

Common situations: Retrying a resume after the drop already finished, passing a wrong/stale table id, or attempting resume on a table that was never dropped.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
