schema

问题 I am trying to create a sample .avro file containing bytes as type and decimal as logicalType, But the avro file when loaded to hive table results in a different value. What could be the reason? schema.avsc: { "type" : "record", "name" : "example", "namespace" : "com.xyz.avro", "fields" : [ { "name" : "cost", "type" : { "type" : "bytes", "logicalType" : "decimal", "precision" : 38, "scale" : 10 } }] } data.json: { "cost" : "0.0" } Converted to .avro using avro-tools : java -jar avro-tools-1.8

问题 I am trying to embed schemas in other schemas that I have created, and I keep getting this error: I am not entirely sure what is going wrong here, but what I want to do is store references to my event schema and interests schema inside the user schema. If someone could tell me what I'm doing wrong that would be great thanks! EDIT: I am now receiving a new error: /Users/Dynee/node_modules/mongoose/lib/schema.js:421 throw new TypeError('Invalid value for schema Array path `' + prefix + key + '`

问题 Is there any tool able to create an AVRO schema from a 'typical' JSON document. For example: { "records":[{"name":"X1","age":2},{"name":"X2","age":4}] } I found http://jsonschema.net/reboot/#/ which generates a ' json-schema ' { "$schema": "http://json-schema.org/draft-04/schema#", "id": "http://jsonschema.net#", "type": "object", "required": false, "properties": { "records": { "id": "#records", "type": "array", "required": false, "items": { "id": "#1", "type": "object", "required": false,

问题 I need to mix "record" type with null type in Schema. "name":"specShape", "type":{ "type":"record", "name":"noSpecShape", "fields":[ { "name":"bpSsc", "type":"null", "default":null, "doc":"SampleValue: null" },... For example, for some datas specShape may be null. So if I set type to "name":"specShape", "type":{ **"type":["record", "null"],** "name":"noSpecShape", "fields":[ { "name":"bpSsc", "type":"null", "default":null, "doc":"SampleValue: null" },... it says No type: {"type":["record",
