Research direction

Start at the REST Catalog alterTable entry point and inspect its NoSuchResourceException handling for 404 resource types beyond TABLE and COLUMN. Compare the analogous createBranch default branch mentioned in the issue. Done means an unmapped 404, such as a DATABASE not-found, no longer returns silent success; verify the concurrent-database-drop reproduction reports an error.

Description

  • I searched in the issues and found no similar issues.
Paimon version

master (1.5-SNAPSHOT)

Compute Engine

Any engine using the REST Catalog.

Minimal reproduce step
  1. Use a REST catalog.
  2. Call alterTable(identifier, changes, ignoreIfNotExists = false) in a situation where the REST server answers with a 404 whose resource type is neither TABLE nor COLUMN, for example a DATABASE not-found because the table's database was concurrently dropped.
What doesn't meet your expectations?

alterTable returns normally and reports success even though the ALTER did not apply. The NoSuchResourceException handler only covers the TABLE and COLUMN resource types; for any other type it falls through the if/else-if chain and the method returns without error, so a failed alter is silently swallowed.

Anything else?

The sibling createBranch already rethrows in the analogous default branch of the same kind of dispatch. alterTable was the only one that let an unmapped 404 fall through to silent success.
