執行spark-submit時出錯

creat res 足夠 sna ring reduce update rim got

執行任務如下:

# ./spark-submit --class org.apache.spark.examples.SparkPi  /hadoop/spark/examples/jars/spark-examples_2.11-2.4.0.jar 100  

報錯如下:

從報錯看出來,,任務一直在請求,但是executor莫名退出了,日誌後面還有一個警告,如下:

2019-02-22 09:42:58 WARN  TaskSchedulerImpl:66 - Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered and have sufficient resources

分析:從這個信息可以看出來,,task沒有獲取到資源

解決:

第一種情況:資源不足(可能是CPU,也可能是內存),這種情況可以調整內存(driver或者executor)或者CPU大小

例如,按如下調整,很多情況都是executor內存設置的過大,超出了實際的內存大小

# ./spark-submit --class org.apache.spark.examples.SparkPi  --executor-memory 512M --total-executor-cores 2 --driver-memory 512M /hadoop/spark/examples/jars/spark-examples_2.11-2.4.0.jar 100   

第二種情況:也是我遇到的。我有一個spark集群+一個spark客戶端,我在spark集群裏面執行任務可以正常執行,但是放到spark客戶端執行的時候就報錯了。機器內存,cpu都足夠大。導致錯誤的原因竟然是主機名和ip對應出錯了,

由於spark集群是以前搭建的,今天做了一個spark,忘記在spark集群裏面添加spark客戶端的主機和ip映射了。添加上好了。

總結:

出現這類問題一般有幾個可能的原因,逐一檢查排除即可:

1.因為提交任務的節點不能和worker節點交互,因為提交完任務後提交任務節點上會起一個進程,展示任務進度,大多端口為4044,工作節點需要反饋進度給該該端口,所以如果主機名或者IP在hosts中配置不正確。所以檢查下主機名和ip是否配置正確。

2.也有可能是內存不足造成的。內存設置可以根據情況調整下。另外,也檢查下web UI看看,確保worker節點處於alive狀態。
