Thrift JDBC Server DescriptionThrift JDBC Server uses the HIVESERVER2 implementation of HIVE0.12. Ability to use Spark or hive0.12 versions of Beeline scripts to interact with JDBC server. The Thrift JDBC server default listening port is 10000.Before using Thrift JDBC Server, you need to be aware of:1, copy the Hive-site.xml configuration file to the $spark_home/conf directory;2. Need to add JDBC-driven jar packages to Spark_classpath in $spark_home/conf/spark-env.shExport Spark_classpath= $SPAR
, application_1537326594090_5664 is the spark task corresponding to the action. Why is there another step in the middle,
In brief, when oozie executes an action, that is, actionexecutor (the main subclass is javaactionexecutor, and actions such as hive and spark are subclasses of this class). javaactionexecutor will first submit a launchermapper (MAP task) in yarn, launchermain is executed (the specific action is its subclass, such as javamain and sparkmain), spark runs sparkmain, and org. apach
good! 3. Show/Hide jar files in the projectdifferent developers have his own habits, and some people think it's too annoying and uncomfortable to show the jar package in the development view. And some people, he would like to look at exactly what technology to use, import which jar package, and by clicking on the jar package in the class file directly view the source code (assuming the previous import source). So, there's a problem with the display and hiding of a jar package: In the Packages E

One way to fix are to copy Jaxws-api.jar and Jaxb-api.jar into JRE endorsed directory, which is$java_home/lib/endorsed (or $JDK _home/jre/lib/endorsed)
Some application containers, such as Glassfish, modifies the location of the endorsed directory to a different place. From inside to the JVM, you can check the current location by DoingSystem.out.println (System.g

Note that even in windows, the path separator is slash (/) instead of back slash (\). sometimes, back slash is OK, but occasionally it causes problems. so using slash is suggested according to my personal experience.
