齊柏林火花RDD命令失敗火花殼工作尚未

Question

我已經建立了獨立的單個節點「集羣」運行下列：

• 卡桑德拉2.2.2
• 星火1.5.1
• 列表項
• 編譯脂肪罐用於火花卡桑德拉 - 連接器1.5.0-M2
• 編譯齊柏林0.6快照 編譯： MVN -Pspark-1.5 -Dspark.version = 1.5.1 -Dhadoop.version = 2.6.0 -Ph adoop-2.4 -DskipTests清潔套裝

我可以工作與卡桑德拉

我已經改變了Zeppelin-env.sh如下火花外殼檢索數據完美的罰款：

export MASTER=spark://localhost:7077 
export SPARK_HOME=/root/spark-1.5.1-bin-hadoop2.6/ 
export ZEPPELIN_PORT=8880 
export ZEPPELIN_JAVA_OPTS="-Dspark.jars=/opt/sparkconnector/spark-cassandra-connector-assembly-1.5.0-M2-SNAPSHOT.jar -Dspark.cassandra.connection.host=localhost" 
export ZEPPELIN_NOTEBOOK_DIR="/root/gowalla-spark-demo/notebooks/zeppelin" 
export SPARK_SUBMIT_OPTIONS="--jars /opt/sparkconnector/spark-cassandra-connector-assembly-1.5.0-M2-SNAPSHOT.jar --deploy-mode cluster" 
export ZEPPELIN_INTP_JAVA_OPTS=$ZEPPELIN_JAVA_OPTS 

然後我開始向筆記本添加段落並首先輸入以下內容：

import com.datastax.spark.connector._ 
import com.datastax.spark.connector.cql._ 
import com.datastax.spark.connector.rdd.CassandraRDD 
import org.apache.spark.rdd.RDD 
import org.apache.spark.SparkContext 
import org.apache.spark.SparkConf 

不確定是否所有這些都是必需的。本段運行良好。

然後我做到以下幾點：

val checkins = sc.cassandraTable("lbsn", "checkins") 

這運行正常，並返回：

checkins: com.datastax.spark.connector.rdd.CassandraTableScanRDD[com.datastax.spark.connector.CassandraRow] = CassandraTableScanRDD[0] at RDD at CassandraRDD.scala:15 

然後在下一段 - 後續2個語句運行-the第一成功和失敗，第二次：

checkins.count 
checkins.first 

結果：

res13: Long = 138449

爲什麼呼叫首先失敗。諸如sc.fromTextFile的調用也失敗。

以下也適用：

checkins.where("year = 2010 and month=2 and day>12 and day<15").count() 

但這並不：

checkins.where("year = 2010 and month=2 and day>12 and day<15").first() 

請幫助，因爲這是推動我瘋了。特別是因爲火花外殼工作，但這不，或至少似乎部分破碎。

感謝

當是兩個或兩個以上的版本在classpath傑克遜庫發生此異常。

確保您的Spark解釋器流程在類路徑中只有一個版本的jackson庫。
