[jira] [Updated] (PIG-2910) Make toString() methods on Schema and
FieldSchema be readable by Utils.getSchemaFromString()
[ https://issues.apache.org/jira/browse/PIG-2910?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Russell Jurney updated PIG-2910:
--------------------------------
Description:
I want to toString() schemas and send them to the backend via UDFContext. At the moment this requires writing your own toString() method that Utils.getSchemaFromString() can read. Making a readable schema for the backend would be an improvement.
I spoke with Thejas, who believes this is a bug. The workaround for the moment is, for example:
String schemaString = inputSchema.toString().substring(1, inputSchema.toString().length() - 1);
// Set the input schema for processing
UDFContext context = UDFContext.getUDFContext();
Properties udfProp = context.getUDFProperties(this.getClass());
udfProp.setProperty("horton.json.udf.schema", schemaString);
...
schema = Utils.getSchemaFromString(strSchema);
