.apply(Combine.globally(Max.ofDoubles()))
liyuntian created BEAM-2479:
-------------------------------
Summary: get MAX value from PCollection<Double> .apply(Combine.globally(Max.ofDoubles()))
Key: BEAM-2479
URL: https://issues.apache.org/jira/browse/BEAM-2479
Project: Beam
Issue Type: Test
Components: runner-spark
Reporter: liyuntian
Assignee: Amit Sela
PCollection<Double> doublePCollectionValue = doublePCollection.apply(Combine.globally(Max.ofDoubles()));
How Can I get Max Value directly from doublePCollectionValue .
Now I write doublePCollectionValue to hdfs using doublePCollectionValue .apply(TextIO.write().to(hdfsPath).withoutSharding()); Is there any method or class which I can use to get MAX value?
