我對Spark的知識是有限的，讀完這個問題後你會感覺到它。我只有一個節點和火花，hadoop和紗線安裝在它上面。屬性spark.yarn.jars - 如何處理它？
我能夠代碼和下面的命令
spark-submit --class com.sanjeevd.sparksimple.wordcount.JobRunner
--master yarn
--deploy-mode cluster
--driver-memory=2g
--executor-memory 2g
--executor-cores 1
--num-executors 1
SparkSimple-0.0.1SNAPSHOT.jar
hdfs://sanjeevd.br:9000/user/spark-test/word-count/input
hdfs://sanjeevd.br:9000/user/spark-test/word-count/output
只是正常運行羣集模式字計數問題。
現在我明白了'spark on yarn'需要集羣上可用的spark jar文件，如果我什麼都不做，那麼每次運行我的程序時都會將數百個jar文件從$ SPARK_HOME複製到每個節點在我的情況下，它只是一個節點）。我看到代碼的執行在完成複製之前暫停了一段時間。請參閱以下內容 -
16/12/12 17:24:03 WARN yarn.Client: Neither spark.yarn.jars nor spark.yarn.archive is set, falling back to uploading libraries under SPARK_HOME.

Spark的文檔建議設置spark.yarn.jars屬性以避免此複製。所以我在spark-defaults.conf文件中設置了以下屬性。
spark.yarn.jars hdfs://sanjeevd.br:9000//user/spark/share/lib
http://spark.apache.org/docs/latest/running-on-yarn.html#preparations 爲了使星火運行罐子從紗線側進入，您可以指定spark.yarn.archive或spark.yarn.jars。有關詳細信息，請參閱Spark屬性。如果既沒有指定spark.yarn.archive也沒有指定spark.yarn.jars，則Spark將創建一個包含$ SPARK_HOME/jars下所有jar的zip文件並將其上傳到分佈式緩存。
順便說一句，我有所有從本地/opt/spark/jars jar文件到HDFS /user/spark/share/lib。他們的人數是206人。
這使我的罐子失敗。以下是錯誤 -

你知道我做錯了嗎？該任務的日誌說下面 -
Error: Could not find or load main class org.apache.spark.deploy.yarn.ApplicationMaster
我理解錯誤ApplicationMaster類沒有找到，但我的問題是，爲什麼沒有發現 - 在這個類應該是什麼？我沒有裝配jar，因爲我正在使用spark 2.0.1，其中沒有捆綁裝配。
這與spark.yarn.jars屬性有什麼關係？這個屬性是爲了幫助在紗線上運行，應該是這樣。使用spark.yarn.jars時需要額外做些什麼？
感謝您閱讀本問題並提前給予幫助。
Sanjeev嗨，在我的情況下，只有在$ SPAKR_HOME $ /罐罐子得到複製。你如何使自己的jar，即'SparkSimple-0.0.1SNAPSHOT.jar'也複製到hdfs？ – ascetic652
