SchemaUtils Doesn't Show the Actual Reason for Validation Failure

[ankitsultana]

Often when our customers try to deploy, Pinot returns Schema is incompatible with tableConfig with no details about the root-cause. We should try to return the exact reason why the Schema validation had failed.

Lines 170 to 181 in 6a8bdb5

	/**
	* Validates that the schema is compatible with the given table config
	*/
	private static void validateCompatibilityWithTableConfig(Schema schema, TableConfig tableConfig) {
	try {
	TableConfigUtils.validate(tableConfig, schema);
	} catch (Exception e) {
	throw new IllegalStateException(
	"Schema is incompatible with tableConfig with name: " + tableConfig.getTableName() + " and type: "
	+ tableConfig.getTableType(), e);
	}
	}
