我在spark上运行简单查询时遇到了一个问题

select * from table_name

在Hive控制台上，每件事都很好地工作，但是当我执行

select count(*) from table_name

查询终止时出现以下错误：

Query ID = ab_20160515134700_795fc14c-e89b-4172-bcc6-0cfcffadcd88
Total jobs = 1

  set mapreduce.job.reduces=<number>

我在hive-site.xml中设置了：spark.master，现在得到了：java.util.concurrent.executionexception:java.lang.runtimeexception:cancel client'8ffe7ea3-aaf4-456c-ae18-23c572a766c5'。错误：子进程在连接回io.netty.util.concurrent.abstractfuture.get（abstractfuture）之前退出。java:37)~[netty-all-4.0.23.最终。jar:4.0.23.final]在org.apache.hive.spark.client.sparkclientimpl.（sparkclientimpl。java:101)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hive.spark.client.sparkclientfactory.createclient（sparkclientfactory。java:80)[配置单元执行-2.0.0。jar:2.0.0]位于org.apache.hadoop.hive.ql.exec.spark.remotehivesparkclient.createremoteclient（remotehivesparkclient）。java:98)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.exec.spark.remotehivesparkclient.（远程hivesparkclient。java:94)[配置单元执行-2.0.0。jar:2.0.0]位于org.apache.hadoop.hive.ql.exec.spark.hivesparkclientfactory.createhivesparkclient（hivesparkclientfactory）。java:63)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.exec.spark.session.sparksessionimpl.open（sparksessionimpl。java:55)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.exec.spark.session.sparksessionmanagerimpl.getsession（sparksessionmanagerimpl。java:114)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.exec.spark.sparkutilities.getsparksession（sparkutilities。java:131)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.exec.spark.sparktask.execute（sparktask。java:106)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.exec.task.executetask（任务。java:158)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.exec.taskrunner.runsequential（taskrunner。java:101)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.driver.launchtask（driver。java:1840)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.driver.execute（driver。java:1584)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.driver.runinternal（驱动程序。java:1361)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.driver.run（driver。java:1184)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.ql.driver.run（driver。java:1172)[配置单元执行-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.cli.clidriver.processlocalcmd（clidriver。java:233) [配置单元cli-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.cli.clidriver.processcmd（clidriver。java:184)[配置单元cli-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.cli.clidriver.processline（clidriver。java:400)[配置单元cli-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.cli.clidriver.executedriver（clidriver。java:778)[配置单元cli-2.0.0。jar:2.0.0]在org.apache.hadoop.hive.cli.clidriver.run（clidriver。java:717)[配置单元cli-2.0.0。jar:2.0.0]位于org.apache.hadoop.hive.cli.clidriver.main（clidriver。java:645)[配置单元cli-2.0.0。jar:2.0.0]在sun.reflect.nativemethodaccessorimpl.invoke0（本机方法）~[？：1.8.0\u 77]在sun.reflect.nativemethodaccessorimpl.invoke（nativemethodaccessorimpl）。java:62) 在sun.reflect.delegatingmethodaccessorimpl.invoke（delegatingmethodaccessorimpl。java:43)在java.lang.reflect.method.invoke（method。java:498)~[？：1.8.0\u 77]位于org.apache.hadoop.util.runjar.run（runjar。java:221)[spark-assembly-1.6.0-hadoop2.6.0。jar:1.6.0]在org.apache.hadoop.util.runjar.main（runjar。java:136) [spark-assembly-1.6.0-hadoop2.6.0。jar:1.6.0]原因：java.lang.runtimeexception:取消客户端“8ffe7ea3-aaf4-456c-ae18-23c572a766c5”。错误：子进程在连接回org.apache.hive.spark.client.rpc.rpcserver.cancelclient（rpcserver）之前退出。java:180)~[hive-exec-2.0.0.配置单元]。jar:2.0.0]在org.apache.hive.spark.client.sparkclientimpl$3.run（sparkclientimpl。java:450)~[hive-exec-2.0.0.配置单元]。jar:2.0.0]在java.lang.thread.run（线程。java:745) ~[?:1.8.0_77] 16/05/16 18:00:33 [驱动程序]：warn client.sparkclientimpl:子进程已退出，代码为1
我已构建spark 1.6.1和hive 2.0.0，因此错误已更改为：
