hive on spark 编译时遇到的问题

1.官方网站下载spark 1.5.0的源码

2.根据官方编译即可。

export MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m" build/mvn -Pyarn -Phadoop-2.6 -Dhadoop.version=2.6.0 -DskipTests clean package

./make-distribution.sh --name custom-spark --tgz -Phadoop-2.6 -Pyarn

如你使用的版本是scala2.11 可以做以下操作

./dev/change-scala-version.sh 2.11 mvn -Pyarn -Phadoop-2.4 -Dscala-2.11 -DskipTests clean package

不用再执行 ./make-distribution.sh --name custom-spark --tgz -Phadoop-2.4 -Pyarn

然后将./assembly/target/scala-2.11/ spark-assembly-1.5.0-hadoop2.6.0.jar 大约137MB 将其拷贝到$HIVE_HOME/lib下 hive 启动后，

可以执行 set hive.execution.engine=spark; 即可

调试中遇到的问题：一定要调YARN的内存，否则会获取不到资源

YARN: Diagnostic Messages for this Task: Container [pid=7830,containerID=container_1397098636321_27548_01_000297] is running beyond physical memory limits.

检查yarn-site-xml job内存限制 <property> <name>yarn.scheduler.minimum-allocation-mb</name> <value>2048</value> </property>

解决方法： 1.增加yarn.scheduler.minimum-allocation-mb内存上限。 2.--hiveconf mapred.child.java.opts=-Xmx？？？？m 一定要小于yarn.scheduler.minimum-allocation-mb

如果是vm超了，如下：调整yarn.nodemanager.vmem-pmem-ratio

查看log没有明显的ERROR，但存在类似以下描述的日志 2012-05-16 13:08:20,876 INFO org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl: Sending out status for container: container_id {, app_attempt_id {, application_id {, id: 18, cluster_timestamp: 1337134318909, }, attemptId: 1, }, id: 6, }, state: C_COMPLETE, diagnostics: "Container [pid=15641,containerID=container_1337134318909_0018_01_000006] is running beyond virtual memory limits.

SRARK 启动时报如下错误： Error: A JNI error has occurred, please check your installation and try again

1. SPARK_DIST_CLASSPATH=$(/home/hadoop/hadoop-2.7.2/bin/hadoop classpath)

2. 解决办法：

3. export SCALA_HOME=/opt/scala-2.11.8 4. export SPARK_MASTER_IP=192.168.233.159 5. export SPARK_WORKER_MEMORY=1g 6. export HADOOP_CONF_DIR=/opt/hadoop-2.6.2/etc/hadoop 7. export JAVA_HOME=/opt/jdk1.8.0_77 8. export SPARK_DIST_CLASSPATH=$(/opt/hadoop-2.6.2/bin/hadoop classpath) ##加这条
