Subject [jira] [Commented] (FLINK-11982) BatchTableSourceFactory support Json Format File
Date Thu, 21 Nov 2019 11:41:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-11982?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16979185#comment-16979185
] 

Nikhil commented on FLINK-11982:
--------------------------------

is this issue fixed, this is not working for filesystem:

 
{code:java}
  
conf.setFloat(ConfigConstants.TASK_MANAGER_MEMORY_FRACTION_KEY,
 memoryFraction.orElseGet(() -> Float.valueOf(taskManagerMemoryFraction)));
final long startFlink = Calendar.getInstance().getTimeInMillis();

ExecutionEnvironment env = ExecutionEnvironment.createLocalEnvironment(conf);
env.setParallelism(parallelism);
BatchTableEnvironment batchTableEnvironment = BatchTableEnvironment.create(env);
batchTableEnvironment.connect(new FileSystem().path("C:/Users/srivnik/test.json")).
 withFormat(new Json().jsonSchema(
 "{" +
 " type: 'object'," +
 " properties: {" +
 " name: {" +
 " type: 'string'" +
 " }," +
 " age: {" +
 " type: 'number'" +
 " }" +
 " }" +
 "}")).registerTableSource("test");
batchTableEnvironment.sqlQuery("select * from test");
{code}

Error:
{code:java}
// Caused by: org.apache.flink.table.api.NoMatchingTableFactoryException: Could not find a
suitable table factory for 'org.apache.flink.table.factories.TableSourceFactory' in
the classpath.Reason: No context matches.The following properties are requested:
connector.path=C:/Users/srivnik/test.json
connector.property-version=1
connector.type=filesystem
format.json-schema={  type: 'object',  properties: {    name: {      type: 'string'    },
   age: {      type: 'number'    }  }}
format.property-version=1
format.type=json

{code}
