URL: https://issues.apache.org/jira/browse/SPARK-21104
Project: Spark
Issue Type: Improvement
Components: MLlib
Affects Versions: 2.1.1
Reporter: darion yaphet
Priority: Minor
When I'm loading LibSVM from HDFS , I found feature index should be in
ascending order . We can sorted with *indices* when we parse the input line
input a (index, value) tuple and avoid check if indices are in ascending order
after that.
