      Description

      I want to create MiniDFSCluster with 2 datanode and for each datanode I want to set different number of StorageTypes, but in this case I am getting ArrayIndexOutOfBoundsException.

      My cluster schema is like this.

      final MiniDFSCluster cluster = new MiniDFSCluster.Builder(conf)
      				.numDataNodes(2)
      				.storageTypes(new StorageType[][] {{ StorageType.DISK, StorageType.ARCHIVE },{ StorageType.DISK } })
      				.build();
      

      Exception :

      java.lang.ArrayIndexOutOfBoundsException: 1
      	at org.apache.hadoop.hdfs.MiniDFSCluster.makeDataNodeDirs(MiniDFSCluster.java:1218)
      	at org.apache.hadoop.hdfs.MiniDFSCluster.startDataNodes(MiniDFSCluster.java:1402)
      	at org.apache.hadoop.hdfs.MiniDFSCluster.initMiniDFSCluster(MiniDFSCluster.java:832)

        { StorageType.DISK }

        })

        The number of datanode directories (i.e. number of storage types) must be the same. Try

        storageTypes(new StorageType[][] {{ StorageType.DISK, StorageType.ARCHIVE },{ StorageType.DISK, StorageType.DISK } })

        Tsz Wo Nicholas Sze Thanks , Yes it will work if number of datanode and number of storage same.
        but for one test case I want to set different. I think we can handle this

        Sure, we could support it.

             assert storageTypes == null || storageTypes.length == storagesPerDatanode;
             for (int j = 0; j < storagesPerDatanode; ++j) {
        +      if ((storageTypes != null) && (j >= storageTypes.length)) {
        +        break;
        +      }
        

        With the assert storageTypes.length == storagesPerDatanode and j < storagesPerDatanode, the condition j >= storageTypes.length is always false. So I guess the patch won't work.

        Tsz Wo Nicholas Sze Thanks for reviewing. I think this assert condition is not working and I am not getting why. When I got ArrayIndexOutOfBoundsException that time storageTypes.length is 1 and storagesPerDatanode is 2 but assert condition didn't failed. I have submitted the patch, we will see the test result here.

        +1 for the latest patch.

        I think this assert condition is not working and I am not getting why.

        May be assertions disabled when you run the test.

        When I run the test with assertion statement in eclipse with "-ea" VM argument, assertion failed.
