Scalardb QA application not properly working with Azure Cosmos DB

问题

I tried to start scalardb backend QA application with Azure Cosmos DB. The Spring boot application shows as started. But I couldn't access the QA backend application with port 8090. Port 8090 does not list in listening ports lsof -i -P -n | grep LISTEN.

QA backend Application

When we connect it with the QA frontend application, it shows an error message An error occurred during the login

QA frontend Application

Step to reproduce

Cosmos DB Account Creation

Create an Azure Cosmos DB account with Core (SQL) API.
Change Default consistency to STRONG .
Create schema using Schema Tool for Scalar DB

schema.json

  "qa.question": {
    "transaction": false,
    "partition-key": [
      "date"
    ],
    "clustering-key": [
      "created_at"
    ],
    "columns": {
      "date": "TEXT",
      "created_at": "BIGINT",
      "title": "TEXT",
      "user": "TEXT",
      "context": "TEXT",
      "updated_at": "BIGINT",
      "number_of_answers": "INT"
    },
    "ru": 400
  },

  "qa.answer": {
    "transaction": false,
    "partition-key": [
      "question_created_at"
    ],
    "clustering-key": [
      "created_at"
    ],
    "columns": {
      "question_created_at": "BIGINT",
      "context": "TEXT",
      "user": "TEXT",
      "created_at": "BIGINT"
    },
    "ru": 400
  },

  "qa.account": {
    "transaction": false,
    "partition-key": [
      "email"
    ],
    "clustering-key": [],
    "columns": {
      "email": "TEXT",
      "password": "TEXT"
    },
    "ru": 400
  },

  "qa.firstQuestionDate": {
    "transaction": false,
    "partition-key": [
      "id"
    ],
    "clustering-key": [],
    "columns": {
      "id": "TEXT",
      "first_question_date": "TEXT"
    },
    "ru": 400
  }
}

QA Backend Application Setup

Application clone from QA application
Update scalardb.properties (backend/QA/src/main/resources/scalardb.properties) file with cosmos db details.

scalardb.properties

# Comma separated contact points
scalar.db.contact_points=<Cosmos DB URI>

# Port number for all the contact points. Default port number for each database is used if empty.
#scalar.db.contact_port=

# Credential information to access the database
scalar.db.username=
scalar.db.password=<PRIMARY KEY>

# Storage implementation. Either cassandra or cosmos can be set. Default storage is cassandra.
scalar.db.storage=cosmos

Update scalardb dependency with lastest version (2.2.0)

build.gradle

....

dependencies {
    //Scalar DB library
    compile group: 'com.scalar-labs', name: 'scalardb', version: '2.2.0'
    //Spring dependencies
    compile("org.springframework.boot:spring-boot-starter-web:${springBootVersion}") {
        exclude(group: 'ch.qos.logback')
    }
    compile("org.springframework.boot:spring-boot-starter:${springBootVersion}") {
        exclude(group: 'ch.qos.logback')
    }
    //Spring security layer for authentication
    compile("org.springframework.boot:spring-boot-starter-security:${springBootVersion}") {
        exclude(group: 'ch.qos.logback')
    }
    //Handle Json Web Token authentication
    compile group: 'io.jsonwebtoken', name: 'jjwt', version: '0.9.1'

    testCompile group: 'org.springframework.boot', name: 'spring-boot-starter-test', version: "${springBootVersion}"
