------------------------------------
Summary: OnlineLDAOptimizer does not handle persistance correctly
Key: SPARK-30503
URL: https://issues.apache.org/jira/browse/SPARK-30503
Project: Spark
Issue Type: Bug
Components: GraphX, ML
Affects Versions: 3.0.0
Reporter: zhengruifeng
It seems that in {{OnlineLDAOptimizer, }}{{PeriodicGraphCheckpointer}} can not
unpersit edges correctly.
