Hello,

 

I have a dataset that is housed in Hadoop HDFS and I would like to perform a proc genmod using this dataset.  For instance, my libname is set as 

libname dchd odbc dsn='xxx' schema='data' dbcommit=99999 insertbuff=99999 readbuff=99999;

 

I have created a dataset called 'ds' that is stored in HDFS as data.ds

 

I now want to perform genmod as follows

 

ods output Estimates=data.output  (keep=event cohort_year Label MeanEstimate MeanLowerCL MeanUpperCL);

 

proc genmod data=data.ds;

model num_event= /d=p link=log offset=log_years;

by event cohort_year;
estimate " " int 1 /exp ;
ods select modelinfo parameterestimates estimates modelfit;
run;

 

The model runs fine but when I try to store an output dataset I get this error:

 

ERROR: During insert: [Simba][ImpalaODBC] (110) Error while executing a query in Impala: [HY000] : AnalysisException: Possible loss
of precision for target table 'aellman.OUTPUTH1'. Expression 'cast(2008 as double)' (type: DOUBLE) would need to be cast to
DECIMAL(11,0) for column 'cohort_year'

 

I am running Enterprise Guide 7.12

 

Thanks.

Did you try sending the output from genmod to a different library than the source data? I'm not sure that the model procedures' ODS OUTPUT speaks HADOOP for output

Maybe Hadoop is different but the convention is typically libname.memname. 

 

Youre trying to do schemaname.memname 

 

I would try just using the work library for starters though. 

 

Ods output estimates=output;

 

Usually the ODS SELECT statement also precedes the proc, but not a requirement.
