摘要

在云计算基础设施中,由于服务器过载、网络拥塞、硬件故障等故障,用户应用程序的风险发生了显著变化。Hadoop使用一个元数据服务器,即NameNode (NN),它将整个文件系统元数据保存在主内存中。在Hadoop中,与这些凭证元数据相关的I/O操作使NameNode成为单点故障。该系统通过使用观察者工具实现容错,该工具将持续监控神经网络。它主动计算任何崩溃的可能性,在这种情况下,系统将使用次级神经网络运行。

Enhancing NameNode fault tolerance in Hadoop over cloud environment
Risks on user applications has significantly changed in the cloud computing infrastructure because of the failures such as server overload, network congestion, hardware faults, etc. Hadoop uses a single metadata server namely NameNode (NN) which keeps the whole file system metadata in primary memory. In Hadoop, the I/O operations associated with those credential metadata makes NameNode a Single Point of Failure. The system achieves fault tolerance by using an Observer Tool, which will continuously monitor the NN. It proactively calculates chances of any crash and in such a case system will run using the secondary NN.
