Problem removing ${versionName} from ${this}

Error message

Problem removing ${versionName} from ${this}

What it means

Inside deleteKey's loop over key versions, keyStore.containsAlias(versionName) or keyStore.deleteEntry(versionName) threw a KeyStoreException, which the provider wraps as IOException 'Problem removing <name>@N from <uri>'. The failure is at the JCE KeyStore level, not the key-name level: the store itself could not perform the entry removal.

Solutions

1. Confirm the store is readable and healthy: `hadoop key list -provider <uri>` (exercises load and getKeys)
2. Remove stale *_NEW/_OLD side files from an interrupted flush, then retry the delete
3. Restore the keystore from backup if entries are corrupt
4. Ensure a single process writes a given keystore file at a time

Set<String> keys = new HashSet<>(provider.getKeys());
if (!keys.contains(name)) { /* avoid delete entirely */ }

try { provider.deleteKey(name); } catch (IOException e) { if (e.getCause() instanceof java.security.KeyStoreException) { // keystore-level fault: verify store health, then retry delete once repaired } else { throw e; } }

When it happens

Trigger: A keystore that loaded in a degraded or corrupt state so subsequent operations throw; keystore corruption from an interrupted flush; a security-provider configuration that rejects entry operations; concurrent modification of the underlying file.

Common situations: Keystore file truncated by a crashed process or full disk; a keystore written by an incompatible Java version or provider; two processes writing the same jceks file.
