-------------------
The external memory mode naturally works on distributed version, you can simply set path like
```
data = "hdfs:///path-to-data/#dtrain.cache"
data = "hdfs://path-to-data/#dtrain.cache"
```
xgboost will cache the data to the local position. When you run on YARN, the current folder is temporal
so that you can directly use ```dtrain.cache``` to cache to current folder.
