Once you have configured your cluster and started running jobs, life will happen, and you may need to recover from a failure. Here, we will look at how HDFS protects from many individual failures and how to recover from other failures. HDFS has two types of data, with different reliability requirements and recovery patterns. The NameNode stores the file system metadata and provides direct replication of the data and run-behind remote copies of the data. The DataNodes provide redundant storage by replicating data blocks to multiple DataNodes.

The default Hadoop installation provides no protection from catastrophic NameNode server failures. The only default protection is that provided by a RAID 1 or RAID 5 storage device for the file system image and edit logs. You can avoid data loss and unrecoverable machine failures by running the secondary NameNode on an alternate machine. Storing the file system image and file system edit logs on multiple physical devices, or even multiple physical machines, also provides protection. When a NameNode server fails, best practices require that all the JobTracker and TaskTrackers be restarted after the NameNode is restarted. All incomplete HDFS blocks will be lost, but there should be no file or data loss for existing files or for completed blocks in actively written files.

The hardware of J2ME devices varies greatly: memory, screen resolutions, color depth, network technologies, inclusion of cameras . . . you name it. If you need specific hardware features, you can use the device selection mechanism of J2ME Polish. Listing 14-1 demonstrates how you can select all phones that have an integrated camera in your build.xml file. Your application is then built only for devices that meet your requirements. I discussed this in detail in the Building for Multiple Devices section of 7.

Current device screens range from 128 128 pixels in Nokia Series 40 phones to 640 320 pixels in high-end devices. Often you will want to use adjusted graphics for the best perception. You can use device groups, vendor devices, and even canvas sizes in fullscreen mode for assembling the best-suited resources. For example, you can put your general resources into the resources folder and put the images for devices with big screens into the resources/ScreenSize.150+x200+ directory. Please refer to the Resource Assembling section in 7 for more information about this option.

The NameNode may be configured to write the metadata log to multiple locations on the host server s file system. In the event of data loss or corruption to one of these locations, the NameNode may be recovered by repairing or removing the failed location from the configuration, removing the data from that location, and restarting the NameNode. For rapid recovery, you may simply remove the failed location from the configuration and restart the NameNode. If the NameNode needs to be recovered from a secondary NameNode, the procedure is somewhat more complex. Here are the steps: 1. Shut down the secondary NameNode. 2. Copy the contents of the Secondary:fs.checkpoint.dir to the Namenode:dfs.name.dir. 3. Copy the contents of the Secondary: fs.checkpoint.edits.dir to the Namenode:dfs.name.edits.dir. 4. When the copy completes, you may start the NameNode and restart the secondary NameNode. All data written to HDFS after the last secondary NameNode checkpoint was taken will be removed and lost. The default frequency of the checkpoints is specified by the fs.checkpoint. period parameter At present, there are no public forensic tools that will recover data from blocks on the DataNodes.
