java.lang.NoSuchMethodError: breeze.linalg.tile$.tile_DM_Impl2

Question

我有一个使用微风的火花代码。我可以看到我的项目的微风版本：

$ 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_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_2.11:0.12
|    |    |    |    +--- org.scalanlp:breeze-macros_2.11:0.12
|    +--- org.scalanlp:breeze_2.11:0.12 (*)

spark 2.1.1中包含的breeze版本是0.12。我可以在spark jars目录中看到以下内容：

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

但是当我提交作业给spark (甚至是本地)时，我得到了这个错误：

java.lang.NoSuchMethodError: breeze.linalg.tile$.tile_DM_Impl2(Lscala/reflect/ClassTag;Lbreeze/storage/Zero;Lbreeze/generic/UFunc$InPlaceImpl2;)Lbreeze/generic/UFunc$UImpl2;

使用的命令行：

spark-2.1.1-bin-hadoop2.4/bin/spark-submit --class my.Main myjar.jar

Answer 1

找到问题了：

我的SPARK_HOME环境变量设置为旧的spark版本。

所以bin/spark-class在另一条路径中寻找jars依赖项
