Review Comment:
why do we need 2 hashmaps? how about this
````
private static Map<String, String> getCatalogProperties(Configuration
conf, String catalogName, String catalogType) {
Map<String, String> catalogProperties = Maps.newHashMap();
Stream<String> includePrefixes = Stream.of(
InputFormatConfig.CATALOG_DEFAULT_CONFIG_PREFIX,
InputFormatConfig.CATALOG_CONFIG_PREFIX + catalogName + "."
);
conf.forEach(config ->
includePrefixes.filter(key -> config.getKey().startsWith(key))
.findAny().ifPresent(keyPrefix ->
catalogProperties.put(config.getKey().substring(keyPrefix.length()),
config.getValue())
)
);
return addCatalogPropertiesIfMissing(conf, catalogType,
catalogProperties);
}
