Major Description
See the following source code:
org.apache.tajo.storage.avro.AvroUtil.java
String schemaURL = meta.getOption(StorageConstants.AVRO_SCHEMA_URL);
Path schemaPath = new Path(schemaURL);
FileSystem fs = schemaPath.getFileSystem(conf);
FSDataInputStream inputStream = fs.open(schemaPath);
Currently, Avro schema URL only support HDFS and S3. But, it does not support HTTP and others. HTTP-based schema is very usual in this field. We need to improve it to support HTTP.
