issues when using the benchmark for TVStore

[panagiotisl]

Hello, I am trying to execute the benchmark for TVStore and I am facing multiple issues:

The most important one is the following exception:

Exception in thread "0-appender" java.lang.NullPointerException: Cannot invoke "org.apache.iotdb.db.service.IoTDB.insertBatch(org.apache.iotdb.db.qp.physical.crud.BatchInsertPlan)" because "this.tvstore" is null

It seems that this variable is never initialized:

    private IoTDB tvstore;
    
    public TVStore(String directory) {
        super(directory);
    }

I have made the changes below:

    public TVStore(String directory) {
        super(directory);
        this.tvstore = new IoTDB();
    }

Which lead to the following error:

Exception in thread "0-appender" java.lang.NoClassDefFoundError: Could not initialize class org.apache.iotdb.db.engine.StorageEngine

Can you please provide guidance on how to execute the benchmark for TVStore?

Hi, this was my mistake, thanks for pointing it out. I have fixed this bug and hope it will help you. The key point is that the initialization of TVStore should be:

public TVStore(String directory) {
    super(directory);
    this.tvstore = IoTDB.getInstance();
    this.tvstore.active();
}
