Bonjour,

Dans l'execution du programme "Compteur de mots" version Pig en mode local, toutes les commandes marchent bien sauf "store" donne l'erreur suivante:

Bonjour,

Si j'en crois ton message d'erreur : 

Failed to read data from "file:///home/soukaina/Bureau/hdfile"


... j'en déduis que parmi les explications possibles, il y a :
- le chemin vers le fichier d'entrée est faux
- le fichier n'a pas des droits suffisants pour être lu par le profil utilisateur qui lance l'application que tu mentionnes
- le fichier est corrompu ou n'a pas le format attendu par ton logiciel.

Bonne chance

mais les commandes DUMP C & DUMP D ont retourné le resultat attendu c'est à dire le probléme n'est qu'au niveau de la commande STORE E

Ce n'est pas vraiment mon domaine, mais l'erreur est : 

Failed Jobs: 
JobId Alias Feature Message Outputs 
job_local1472906397_0003 A,B,C,D,E GROUP_BY,COMBINER Message: Job failed! file:///home/soukaina/Bureau/results,


Du coup peut être que parmi A,B,C,D,E l'un des jobs a planté, ou en peut être que le résultats ne sont pas homogène et ne permettent pas de faire le "GROUP BY". As-tu regardé si ces 5 variables contenaient le résultat attendu ?

Bonne chance

Oui ces 5 variables contiennent le résultat attendu.
en fait j'ai exécuté un programme pareil en mode mapreduce et tout a bien marché même la commande STORE
le problème reste au niveau de la commande STORE en mode local.

merci.

Alors, ce n'est pas du tout ma spécialité, mais je vois le mot clé GROUP BY, COMBINER.

- Est-ce que cette primitive a du sens par rapport à chacuns des résultats observés dans A,B,C,D,E ?

- As-tu essayé de l'appliquer progressivement (à A, puis A,B, etc... pour localiser la cause du problème) ?
