Load balancing Hadoop distributed file system operations in a non-native operating system
Implementations are provided herein for utilizing the two-part nature of HDFS protocol communications received in a non-native HDFS environment to use discriminative information learned in the NameNode request to make the client experience more efficient. NameNode requests can be received by any node among a cluster of nodes.

Methods for isolating portions of a loop of pitch-multiplied material and related structures
Different portions of a continuous loop of semiconductor material are electrically isolated from one another. In some embodiments, the end of the loop is electrically isolated from mid-portions of the loop. In some embodiments, loops of semiconductor material, having two legs connected together at their ends, are formed by a pitch multiplication process in which loops of spacers are formed on sidewalls of mandrels. The mandrels are removed and a block of masking material is overlaid on at least one end of the spacer loops. In some embodiments, the blocks of masking material overlay each end of the spacer loops. The pattern defined by the spacers and the blocks are transferred to a layer of semiconductor material. The blocks electrically connect together all the loops. A select gate is formed along each leg of the loops. The blocks serve as sources/drains. The select gates are biased in the off state to prevent current flow from the mid-portion of the loop's legs to the blocks, thereby electrically isolating the mid-portions from the ends of the loops and also electrically isolating different legs of a loop from each other. |
