J'ai un code spark qui utilise brise. Je peux voir la version brise de mon projet:
$ gradle dependencies | grep breeze
| | +--- org.scalanlp:breeze_2.11:0.12
| | | +--- org.scalanlp:breeze-macros_2.11:0.12
+--- org.scalanlp:breeze_2.11:0.12 (*)

| | +--- org.scalanlp:breeze_2.11:0.12
| | | +--- org.scalanlp:breeze-macros_2.11:0.12

| | | +--- org.scalanlp:breeze_2.11:0.12
| | | | +--- org.scalanlp:breeze-macros_2.11:0.12

| | | | +--- org.scalanlp:breeze-macros_2.11:0.12
| +--- org.scalanlp:breeze_2.11:0.12 (*)
La version de breeze incluse dans étincelle 2.1.1 est 0.12. Je peux voir cette recherche dans le répertoire des pots d'allumage:
spark-2.1.1-bin-hadoop2.4$ find . -name *.jar | grep breeze
./jars/breeze_2.11-0.12.jar
./jars/breeze-macros_2.11-0.12.jar
Mais quand je soumets la tâche à susciter (même local) je reçois cette erreur:
java.lang.NoSuchMethodError: breeze.linalg.tile$.tile_DM_Impl2(Lscala/reflect/ClassTag;Lbreeze/storage/Zero;Lbreeze/generic/UFunc$InPlaceImpl2;)Lbreeze/generic/UFunc$UImpl2;
