public class ValidateSchemaForAvroStores
extends java.lang.Object

Input: 1. Absolute path to a Directory which may contain stores.xml in its sub directories (OR) 2. Absolute path to a single stores.xml file NOTE: 1. This tool just checks for invalid, partial and non backwards compatible Avro schemas and that it DOESNOT fix invalid/partial/non backwards-compatible schemas 2. It is users responsibility to give right path. 3. Avro types validated: avro-generic and avro-generic-versioned 4. Avro types for which backwards compatibility is checked: avro-generic-versioned 6. Note that avro-specific and avro-reflective are not validated How to check if a schema is valid? Exceptions are thrown otherwise. Look for them and the corresponding store in the log How to know if a valid schema is fully backwards compatible? Grep for "WARN" or "ERROR" in console output for partial/non-backwards compatible avro schemas. If no match for grep then things are good.
