Briefly, this error occurs when an attempt is made to update the mapping of an index that has been set to read-only or has been closed. Elasticsearch does not allow mapping updates in such cases. To resolve this issue, you can either set the index back to read-write mode using the Elasticsearch API or reopen the closed index. Additionally, ensure that the mapping changes are made before the index becomes read-only or gets closed.

 if (result.getResultType() == Engine.Result.Type.MAPPING_UPDATE_REQUIRED) {
 throw new MapperException("mapping updates are not allowed [" + operation + "]");
 }
 if (result.getFailure() != null) {
 if (Assertions.ENABLED && result.getFailure() instanceof MapperException == false) {
 throw new AssertionError("unexpected failure while replicating translog entry"; result.getFailure());
 }
