Parsing variable schema
Here is a snippet of how schema is applied to tuples

String serializedSchema = p.getProperty(signature + SCHEMA_FILE);
                if (serializedSchema != null) {
                    try {
                        resourceSchema = new
                    } catch (ParserException e) {
                        mLog.error("Unable to parse serialized schema " +
serializedSchema, e);
Is there a good way to define multiple "serializedSchema" which could be
applied to different type of tuples (different log lines)? I am able to
push this logic into a UDF to parse a record based on a schema data
structure I build within it. Wondering if this can be done in LoadFunc
