Hi,
In order to build an integrated analytics scenario (Batch, Realtime and
Predictive) with DAS 3.0.0 tried the following steps in a local server
though by installing and using CEP-ML extension in DAS. The steps followed
are below.
1.) Installed ML 1.1.0 features in DAS 3.0.0.
2) Created a model through ML 1.1.0 .
3.) Publish model to DAS registry .
4.) Use the ML extention through execution plan.
The following exceptions is observed at Server startup, possibly due to
the issue of "supporting multiple Spark context in a jvm"[2]. Can start
the server with command wso2server.sh -DdisableAnalyticsSparkCtx=true
However this prevents using the batch analytics features in DAS,
Is there a solution to get all three integrated analytics with DAS
3.0.0?Is there a way use the ML model to overcome issue[2]
