WSO2 DAS Spark 脚本无法执行

Question

以下是我尝试执行的 spark 脚本。它在 DAS(3.0.1) 批处理分析控制台上成功运行。但在批处理分析中保存为脚本时无法执行。

insert overwrite table CLASS_COUNT select  ((timestamp / 120000) * 120000) as time , vin , username , classType,        
sum(acceleCount) as acceleCount , sum(decceleCount) as decceleCount
from ACCELE_COUNTS
group by ((timestamp / 120000) * 120000) ,classType, vin, username;

错误：

ERROR: [1.199] failure: ``limit'' expected but identifier ACCELE_COUNTSgroup found insert overwrite table X1234_CLASS_COUNT select ((timestamp / 120000) * 120000) as time , vin , username , classType, sum(acceleCount) as acceleCount , sum(decceleCount) as decceleCountfrom ACCELE_COUNTSgroup by ((timestamp / 120000) * 120000) ,classType, vin, username ^

在此之前，我正在执行以下操作，没有任何问题。

CREATE TEMPORARY TABLE ACCELE_COUNTS 
USING CarbonAnalytics 
OPTIONS (tableName "KAMPANA_RECKLESS_COUNT_STREAM", 
     schema "timestamp LONG , vin STRING, username STRING, classType STRING, acceleCount INT,decceleCount INT");

CREATE TEMPORARY TABLE CLASS_COUNT 
USING org.wso2.carbon.analytics.spark.event.EventStreamProvider 
OPTIONS (receiverURL "tcp://localhost:7611",
     username "admin",
     password "admin",
     streamName "DAS_RECKELSS_COUNT_STREAM", 
     version "1.0.0",
     description "Events are published  when product quantity goes beyond a certain level",
     nickName "product alerts",
     payload "time LONG,vin STRING,username STRING, classType STRING, acceleCount INT, decceleCount INT"
);

Answer 1

发生这种情况是因为您之间没有空格

1) decceleCount 和 from

2) ACCELE_COUNTS 和 group by

因此，即使第二个单词在新行中，也要确保单词之间有空格。
