> .storageTypes(new StorageType[][] {{ StorageType.DISK, StorageType.ARCHIVE
> },{ StorageType.DISK } })
The number of datanode directories (i.e. number of storage types) must be the
same. Try
{code}
storageTypes(new StorageType[][] {{ StorageType.DISK, StorageType.ARCHIVE },{
StorageType.DISK, StorageType.DISK } })
{code}
> ArrayIndexOutOfBoundsException in MiniDFSCluster.
