我能够在spark 1.6.0上以编程方式创建一个hive上下文,使用:
val conf = new SparkConf().setAppName("SparkTest").setMaster("local")
val sc=new SparkContext(conf)
val hc = new HiveContext(sc)
val actualRecordCountHC = hc.sql("select count(*) from hiveorc_replica.appointment")
这对我来说很好。同样,我希望在spark 2.3.
当尝试运行日记节点时,它会失败。有折页错误:
./hadoop-daemon.sh start journalnode

<?xml-stylesheet type="text/xsl" href="configur
@Resource
private PersonRepository personRepository;
@Transactional
@Override
public Person create(PersonDTO created) {
LOGGER.debug("Creating a new person with information: " + created);
Person person = Person.getBuilder(created.getFirstName(), created.getLastName()).build();

Execution failed for task ':checkstyleMain'.

但我得到了例外
