首先,我開始在火花的節儉服務器。 /sbin/start-thriftserver.sh
和deamon開始。火花不支持的方法
hadoop 13015 1 99 13:52 pts/1 00:00:09 /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java -cp /home/hadoop/spark/lib/hive-jdbc-0.13.0.jar:/home/hadoop/spark-1.4.1-bin-hadoop2.6/sbin/../conf/:/home/hadoop/spark-1.4.1-bin-hadoop2.6/lib/spark-assembly-1.4.1-hadoop2.6.0.jar:/home/hadoop/spark-1.4.1-bin-hadoop2.6/lib/datanucleus-core-3.2.10.jar:/home/hadoop/spark-1.4.1-bin-hadoop2.6/lib/datanucleus-api-jdo-3.2.6.jar:/home/hadoop/spark-1.4.1-bin-hadoop2.6/lib/datanucleus-rdbms-3.2.9.jar
-Xms512m -Xmx512m -XX:MaxPermSize=256m org.apache.spark.deploy.SparkSubmit --class org.apache.spark.sql.hive.thriftserver.HiveThriftServer2 spark-internal
後,我開始/bin/pyspark
我的蜂巢版本是0.13.1,
火花版本是1.4.1,
的Hadoop版本是2.7
火花類路徑下面。
SPARK_CLASSPATH = /home/account/spark/lib/hive-jdbc-0.13.0.jar: /home/account/spark/lib/hive-exec-0.13.0.jar: /家/account/spark/lib/hive-metastore-0.13.0.jar: /home/account/spark/lib/hive-service-0.13.0.jar: /home/account/spark/lib/libfb303-0.9 .0.jar: /home/account/spark/lib/log4j-1.2.16.jar
在pyspark(蟒蛇殼),我寫了這個代碼。
>>> df = sqlContext.load(source="jdbc",driver="org.apache.hive.jdbc.HiveDriver", url="jdbc:hive2://IP:10000/default", dbtable="default.test")
,但它不工作,我得到這個錯誤。我該如何解決這個錯誤?

我認爲在蜂箱不支持HiveResultSetMetaData.isSigned
方法。 但我不知道如何解決此錯誤。請幫忙..
謝謝
