> Key: HIVE-7347
> URL: https://issues.apache.org/jira/browse/HIVE-7347
> Project: Hive
> Issue Type: Bug
> Components: WebHCat
> Affects Versions: 0.12.0, 0.13.0
> Environment: HDP 2.1 on Windows; HDInsight deploying HDP 2.1
> Reporter: Azim Uddin
>
> 1. Consider you are using HDP 2.1 on Windows, and you have a tsv file (named
> rawInput.tsv) like this (just an example, you can use any) -
> http://a.com http://b.com 1
> http://b.com http://c.com 2
> http://d.com http://e.com 3
> 2. With the tsv file uploaded to HDFS, run the following Pig job via WebHcat
> using 'execute' parameter, something like this-
> curl.exe -d execute="rawInput = load '/test/data' using PigStorage as
> (SourceUrl:chararray, DestinationUrl:chararray, InstanceCount:int);
> readyInput = limit rawInput 10; store readyInput into '/test/output' using
> PigStorage;" -d statusdir="/test/status"
> "http://localhost:50111/templeton/v1/pig?user.name=hadoop"; --user hadoop:any
> The job fails with exit code 255 -
> "[main] org.apache.hive.hcatalog.templeton.tool.LaunchMapper: templeton: job
> failed with exit code 255"
> From stderr, we see the following -"readyInput was unexpected at this time."
> 3. The same job works via Pig Grunt Shell and if we use the WebHcat 'file'
> parameter, instead of 'execute' parameter -
> a. Create a pig script called pig-script.txt with the query below and put it
> HDFS /test/script
> rawInput = load '/test/data' using PigStorage as (SourceUrl:chararray,
> DestinationUrl:chararray, InstanceCount:int);
> readyInput = limit rawInput 10;
> store readyInput into '/test/Output' using PigStorage;
> b. Run the job via webHcat:
> curl.exe -d file="/test/script/pig_script.txt" -d statusdir="/test/status"
> "http://localhost:50111/templeton/v1/pig?user.name=hadoop"; --user hadoop:any
> 4. Also, WebHcat 'execute' option works if we don't define the schema in the
> Pig query, something like this-
> curl.exe -d execute="rawInput = load '/test/data' using PigStorage;
> readyInput = limit rawInput 10; store readyInput into '/test/output' using
> PigStorage;" -d statusdir="/test/status"
> "http://localhost:50111/templeton/v1/pig?user.name=hadoop"; --user hadoop:any
> Ask is-
> WebHcat 'execute' option should work for Pig query with schema defined - it
> appears to be a parsing issue with WebHcat.
