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.
