I am creating an Impala table stored as Kudu using the command as mentioned below.
create table if not exists bit_nnet.bit_feature_matrix_100 comment 'Table to store the feature matrix' stored as kudu as select * from bit_nnet.bit_feature_matrix_100_ext;
The source table "feature_matrix_100_ext" is a regular Impala external table which does not have a primary key. Hence, when I'm trying to create the table, getting an error that a primary key is required for a Kudu table (which is quite natural)!
The following is the error I'm getting:
AnalysisException: A primary key is required for a Kudu table.
Any idea how to overcome this issue?
Note: I am using the Hue interface for doing the aforesaid

there is a uuid function in impala that you can use to generate surrogate keys for kudu. or you can write an impala udf to generate unique bigints.
