Error message

Deprecated

What it means

getOutstandingSchemaVersions() (Map keyed by schema UUID to InetAddress sets) was deprecated in 4.0 (CASSANDRA-13983/CEP-21, host+port schema coordination) and is now permanently removed: the method unconditionally throws RuntimeException("Deprecated"). It exists only as a stub for the StorageServiceMBean interface.

Solutions

1. Switch to getOutstandingSchemaVersionsWithPort(), which returns Map<String, Set<String>> with host:port addresses.
2. Remove calls from tooling; use nodetool describecluster to inspect schema disagreement instead.
3. Update MBean clients to the current StorageServiceMBean interface.

Example fix

// before
Map<String, Set<InetAddress>> v = ss.getOutstandingSchemaVersions(); // throws
// after
Map<String, Set<String>> v = ss.getOutstandingSchemaVersionsWithPort();

try { return ss.getOutstandingSchemaVersions(); } catch (RuntimeException e) { return schemaVersionsViaDescribecluster(); }

When it happens

Trigger: Any call to StorageService.getOutstandingSchemaVersions() — via JMX, nodetool, or client code built against the 4.0-era MBean.

Common situations: Legacy monitoring/automation code compiled or scripted against pre-CEP-21 MBean signatures calling into a 4.1+ cluster; JMX consoles invoking the deprecated attribute.
