Create a time series window with Spark SQL in WSO2 DAS - wso2

Question

I need to create a time series window to do some analysis in WSO2 DAS.
Suppose we have a sensor that each second sends a "fault" attribute and a "temperature" attribute:
{"fault": false, "temperature": 29}
{"fault": false, "temperature": 21}
{"fault": false, "temperature": 30}
{"fault": false, "temperature": 28}
{"fault": false, "temperature": 23}
{"fault": false, "temperature": 22}
{"fault": false, "temperature": 26}
Then we want to create a window of 2 consecutive temperature values:
t1, t2
------
29, 21
21, 30
30, 28
etc...
In order to do this I try to run in the Interactive Analytics Console a spark SQL query like this:
CREATE TEMPORARY TABLE SAMPLE_TYPE_EVENTS USING CarbonAnalytics OPTIONS (tableName "IOT_PER_DEVICE_STREAM_CARBON_SUPER_SAMPLETYPE", recordStore "EVENT_STORE", schema "temperature INT,fault BOOLEAN,meta_deviceId STRING, _timestamp LONG");
SELECT temperature, LAG(temperature) OVER (PARTITION BY meta_deviceId ORDER BY _timestamp) FROM SAMPLE_TYPE_EVENTS;
but I get the following error:
TID: [-1234] [] [2017-09-29 17:02:21,075] ERROR {org.wso2.carbon.analytics.spark.admin.AnalyticsProcessorAdminService} - Error while executing query : select temperature, lag(temperature) over (partition by meta_deviceId order by _timestamp) FROM SAMPLE_TYPE_EVENTS; {org.wso2.carbon.analytics.spark.admin.AnalyticsProcessorAdminService}

Why am I getting this error?
For those of you that don't know WSO2 DAS, it is a GUI that wraps the spark environment, so I don't have some "code" but only the SQL query that i paste into a console like this:
