Error Reported When Parsing Algorithm Parameter Values

Symptom

When an algorithm is run, the log shows that the parameters prefixed with spark.boostkit are incorrectly parsed. Then, the program automatically stops. For example, if the parameters of the PrefixSpan algorithm are incorrectly set, the following log will be displayed:

parse boostkit parameter(spark.boostkit.ml.ps.localTimeout) failed, Error reason: ...

Key Process and Cause Analysis

The spark conf parameters newly added to the algorithms are all prefixed with spark.boostkit. If the parameter value does not meet the requirements, a parsing error occurs.

Conclusion and Solution

Change the parameter values. For details, see Algorithm APIs.
