Hi:

After get data with pig from hive, now i am inserting with this command

F = STORE E INTO 'journey_pig' USING org.apache.hive.hcatalog.pig.HCatStorer();

the F has this records:

(STR03CON,3190,2015-12-06 00,9992,2015,12,1)
(STS01OON,3081,2015-12-06 00,9154,2015,12,1)
(VAO13MOU,3076,2015-12-06 00,9554,2015,12,1)
(VMP71MOU,9998,2015-12-06 00,0001,2015,12,11)

and the error is:

2016-02-15 17:22:42,483 [main] ERROR org.apache.pig.tools.grunt.Grunt - org.apache.pig.impl.plan.VisitorException: ERROR 1115:

Hi:

Finally it worked like this:

e = load 'hdfs://localhost:8020/tmp/jofi_pig_temp' using PigStorage(',') AS (codtf : chararray,codnrbeenf : chararray, fechaoprcnf : chararray, codinternouof : chararray, year : chararray, month : chararray, frecuencia : int);

Many thanks

@Roberto Sancho

You have to specify the schema in your load statement. See this example

@Roberto Sancho I am taking this from previous questions

F = LOAD 'journey_pig' USING org.apache.hive.hcatalog.pig.HCatLoader();

The above statement needs a schema.

For example:

F = LOAD 'journey_pig' USING org.apache.hive.hcatalog.pig.HCatLoader() as (name : chararray, number : int .....)

You don't to STORE the relationship into 'F'. Just issue the store command.

Also, please describe 'E' and see the list of column name that you are storing into the hive table. Make sure the column names align and mentioned in lower case in your relationship.

If you don't see the field name in the relationship, then you can define one as follows:

F = FOREACH E GENERATE (chararray)$0 as (col1:chararray), (chararray)$1 as (col2:chararray), .... etc...

and STORE F INTO 'journey_pig' using HCatStorer();

Hope this helps!

Thanks!

@Roberto Sancho it is complaining about column #4, check your table schema and explicitly specify the column schema. Please run

describe table; 

in Hive and

describe E; 

in pig. We can compare. Also you don't need to say "F = STORE E", just issue STORE E INTO 'path' using ...;

Hi:

my problem is that, i created F like this:

E = FOREACH D GENERATE
    FLATTEN(group),
    COUNT(C);


and y dont know where y put in the flatten the parameter for the colum.

Many thanks egain

Hi:

STORE E INTO 'hdfs://lnxbig05.cajarural.gcr:8020/tmp/journey_pig_temp' using PigStorage(',');
F = load 'hdfs://lnxbig05.cajarural.gcr:8020/tmp/journey_pig_temp/pig_temp.out' using PigStorage(',');
G = foreach A generate $0, $1, $2, $3, $4, $5, $6, $7;
dump G;
STORE G INTO 'default.journey_pig' USING  org.apache.hive.hcatalog.pig.HCatStorer();

this is the hdfs://lnxbig05.cajarural.gcr:8020/tmp/journey_pig_temp file

@Roberto Sancho can you run use default; describe journey_pig; in hive. In pig I want you to run describe G;
