Hi maheshakya,
I have installed them correctly.now I am trying to debug the siddhi
extention with the cep as the [1] describes. But when i created an input
stream and a predictionStream (output stream). when i was trying to create
new execution plan with above streams i got error when i clicked "Validate
Query Expression".Error was,
Error:
No extension exist for StreamFunctionExtension{namespace='ml'} in execution
plan "ExecutionPlan"
and my expression is like a
/* Enter a unique ExecutionPlan */
@Plan:name('ExecutionPlan')
/* Enter a unique description for ExecutionPlan */
-- @Plan:description('ExecutionPlan')
/* define streams/tables and write queries here ... */
@Import('InputStream:1.0.0')
define stream InputStream (NumPregnancies double, TSFT double, DPF double,
BMI double, DBP double, PG2 double, Age double, SI2 double);
@Export('PredictionStream:1.0.0')
define stream PredictionSTream (NumPregnancies double, TSFT double, DPF
double, BMI double, DBP double, PG2 double, Age double, SI2 double, Class
double);
from
InputStream#ml:predict('file:///home/mahesh/GSOC/WSO2/data-set/pima-indian-diabetes.data','double')
select *
insert into PredictionStream
i used file instead of registry. And i referred to the [2] and there they
mention that solution for fixing CEP is running on distributed mode with
apache Storm cluster.
1. Is that CEP i built is originally run as distributed mode?
2. Is this cuased by an not having sudo privilleges in current user when
installing ML features onto CEP?
3.Is this the correct way to give file to CEP.
