Question

当我尝试使用sparkR时，我正在努力解决这个问题。

sparkR.session(master = "local[*]", sparkConfig = list(spark.driver.memory = "1g"))
Error in handleErrors(returnStatus, conn) : 
  java.lang.IllegalArgumentException: Error while instantiating 'org.apache.spark.sql.hive.HiveSessionState':

希望这是一个明确的解决方案，我是新手，我对Java scala一无所知。非常感谢！

Answer 1

我有同样的错误。看起来它与用户权限有关。因此，您有两种选择：

1）从您拥有必要权限的目录中启动sparkR（先决条件：需要在PATH环境变量中包含spark bin文件夹：export PATH=$SPARK_HOME/bin:$PATH）：

cd ~
sparkR

2）使用sudo权限启动sparkR：

/opt/spark/bin $ sudo ./sparkR

请尝试从环境变量中删除btn_Employee.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View vEmployee) { if(btn_Employee.isPressed()) { //markAttendance and generateReport button should be disabled Intent i = new Intent(Selection.this, HomeActivity.class); i.putExtra("BUTTON_CLICK","EMPLOYEE"); startActivity(i); } } }); btn_Employer.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View vEmployer) { Intent i = new Intent(Selection.this, HomeActivity.class); i.putExtra("BUTTON_CLICK","EMPLOYER"); startActivity(i); } });

sparkR：实例化＆＃39; org.apache.spark.sql.hive.HiveSessionState＆＃39;：
