Email Required, but never shown. The Overflow Blog. By replicating edits to a quorum of three JournalNodes, this architecture is able to tolerate the failure of any one node in the system. However, some deployments require higher degrees of fault-tolerance.
This is enabled by this new feature, which allows users to run multiple standby NameNodes. For instance, by configuring three NameNodes and five JournalNodes, the cluster is able to tolerate the failure of two nodes rather than just one.
The HDFS high-availability documentation has been updated with instructions on how to configure more than two NameNodes. Previously, the default ports of multiple Hadoop services were in the Linux ephemeral port range This meant that at startup, services would sometimes fail to bind to the port due to a conflict with another application. A single DataNode manages multiple disks. During normal write operation, disks will be filled up evenly. However, adding or replacing disks can lead to significant skew within a DataNode.
This situation is handled by the new intra-DataNode balancing functionality, which is invoked via the hdfs diskbalancer CLI. A series of changes have been made to heap management for Hadoop daemons as well as MapReduce tasks. MAPREDUCE simplifies the configuration of map and reduce task heap sizes, so the desired heap size no longer needs to be specified in both the task configuration and as a Java option.
Existing configs that already specify both are not affected by this change. This is similar to the existing ViewFs and HDFS Federation functionality, except the mount table is managed on the server-side by the routing layer rather than on the client. This simplifies access to a federated cluster for existing HDFS clients. The OrgQueue extension to the capacity scheduler provides a programmatic way to change configurations by providing a REST API that users can call to modify queue configurations.
For instance, the cluster administrator could define resources like GPUs, software licenses, or locally-attached storage. YARN tasks can then be scheduled based on the availability of these resources.
