The preliminary work is finally over!

In fact, the long road to compilation has only just begun.

Download and compile the Spark source code

Sacrifice a mass murder weapon! = = > refer to the official website

Download & extract the Spark2.4.2 source code cd ~ / sourcewget https://archive.apache.org/dist/spark/spark-2.4.2/spark-2.4.2.tgz# sometimes slow [max@hadoop000 source] $lltotal 15788Murray RW Murray RW Murray. 1 max max 16165557 Apr 28 12:27 spark-2.4.2.tgz [max@hadoop000 source] $tar-zxf spark-2.4.2.tgz about Maven

Instead of using the mvn command, we use the make-distribution.sh script directly, but we need to modify it.

Vim. / dev/make-distribution.sh# under the # spark-2.4.2 folder comments these lines here as a best practice To reduce compilation time # VERSION=$ ("$MVN" help:evaluate-Dexpression=project.version $@ 2 > / dev/null\ # | grep-v "INFO"\ # | grep-v "WARNING"\ # | tail-n 1) # SCALA_VERSION=$ ("$MVN" help:evaluate-Dexpression=scala.binary.version $@ 2 > / dev/null\ # | grep-v "INFO"\ # | grep-v "WARNING"\ # | tail -n 1) # SPARK_HADOOP_VERSION=$ ("$MVN" help:evaluate-Dexpression=hadoop.version $@ 2 > / dev/null\ # | grep-v "INFO"\ # | grep-v "WARNING"\ # | tail-n 1) # SPARK_HIVE=$ ("$MVN" help:evaluate-Dexpression=project.activeProfiles-pl sql/hive $@ 2 > / dev/null\ # | grep-v "INFO"\ # | grep-v "WARNING"\ # | fgrep-count "hive" \ # # Reset exit status to 0, otherwise the script stops here if the last grep finds nothing\ # # because we use "set-o pipefail" # echo-n) # # add a parameter.

In the default library of maven, only apache version of Hadoop is dependent by default, but since our hadoop version is hadoop-2.6.0-cdh6.14.0, we need to add CDH repository to the pom file.

# vim pom.xml central http://maven.aliyun.com/nexus/content/groups/public// true true always fail cloudera https://repository.cloudera.com/artifactory/cloudera-repos/ under the spark-2.4.2 folder starts compilation . / dev/make-distribution.sh\-- name hadoop-2.6.0-cdh6.14.0\-- tgz\-Phadoop-2.6\-Dhadoop.version=2.6.0-cdh6.14.0\-Phive- Phive-thriftserver\-Pyarn\-Pkubernetes

It takes about 1 hour to compile for the first time. I am Aliyun image.

Compiling again will approximately require 10min

Note: if you report an error, you must learn to read the wrong log!

From this we can see that the compiled package is under the spark source package.
