- Method Detail
  - nextDirectory
```
java.lang.String nextDirectory()
```
    Allocate a base directory each call. There may be multi base directories configured by user, generally each base directory represent a disk, allocated by round mode. For example, the base directories configured ["/disk1/job_001/container_001", "/disk2/job_001/container_001"]. It indicates there are two base directories and each base directory for one disk. First call returns "/disk1/job_001/container_001", second call returns "/disk2/job_001/container_001" and third call returns "/disk1/job_001/container_001" and so on in round mode. Note: Can't request a directory and write many files into it, this will cause the io pressure can't distributed over several disks.
    
    Returns:
    
    The directory of allocated local base directory.
