-----------------------------------

Replay bug steps:
 # load mlog.bin [^mlog.bin]
 # exucute `load '/Users/chenyanze/projects/JavaProjects/iotdb/test/1647339089973-1-0-0.tsfile' sglevel=2`

[^1647339089973-1-0-0.tsfile]

 

 

I think this bug is caused by the function isPathExist. If schema template is used, it will update cur by upperTemplate.getDirectNode(nodeNames[i]) and excute cur.getChild(nodeNames[i]) again. Add an else condition before cur.getChild(nodeNames[i]) may solve this problem.

 
{code:java}
//MTree.java

public boolean isPathExist(PartialPath path) {
  String[] nodeNames = path.getNodes();
  IMNode cur = root;
  if (!nodeNames[0].equals(root.getName())) {
    return false;
  }
  Template upperTemplate = cur.getSchemaTemplate();
  for (int i = 1; i < nodeNames.length; i++) {
    if (!cur.hasChild(nodeNames[i])) {
      if (!cur.isUseTemplate() || upperTemplate.getDirectNode(nodeNames[i]) == null) {
        return false;
      }
      cur = upperTemplate.getDirectNode(nodeNames[i]);
    }
    cur = cur.getChild(nodeNames[i]);
    if (cur.isMeasurement()) {
      return i == nodeNames.length - 1;
    }
    upperTemplate = cur.getSchemaTemplate() == null ? upperTemplate : cur.getSchemaTemplate();
  }
  return true;
} {code}

> Hi IoTDBers
>    When I use load function to load tsfile into an iotdb instance,I met an error like below picture:
> !image-2022-03-16-09-17-27-684.png!
> These ts files are made by iotdb-benchmark(and the same iotdb instance).So they has the same schema.
> About the benchmark config please refer to the attachment.
>  # 是否使用template
> TEMPLATE=true
>  # 是否使用vector
> VECTOR=false
> Please help us to check this.
> Thanks！
