[jira] [Commented] (BEAM-2787) IllegalArgumentException with
MongoDbIO with empty PCollection
[ https://issues.apache.org/jira/browse/BEAM-2787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16136254#comment-16136254 ]
Siddharth Mittal commented on BEAM-2787:
----------------------------------------
Possible Resolution :
Class : MongoDbIO
Method Name : Flush
Possible fix :
private void flush() {
if (this.batch != null && this.batch.size() > 0) {
MongoDatabase mongoDatabase = this.client.getDatabase(this.spec.database()); MongoCollection mongoCollection = mongoDatabase.getCollection(this.spec.collection()); mongoCollection.insertMany(this.batch); this.batch.clear();
}
}

> We have read a file and created a PCollection of Strings where each record represent one line on the file. There after we have multiple PTransforms to validate the records. In the end The Pcollection was filtered into two PCollection , one with all valid records and one with all invalid records. Now both the pcollections are stored to respective mongo db collections . In case if any of these pcollection is empty we are facing below exception trace :
