Abstract: Systems and methods for identifying a faulty node in a Hadoop cluster using an interface to the Hadoop cluster are described. A method may include receiving, at an interface to a Hadoop cluster, an input requesting diagnostic information for one or more nodes in the Hadoop cluster. The input may also specify the one or more nodes in the Hadoop cluster for which diagnostic information is requested. The method may further include initiating a diagnostic analysis of the one or more nodes, and displaying, at the interface, the diagnostic information for the one or more nodes. The diagnostic information may identify a node exhibiting a fault and be displayed while the diagnostic analysis is in progress.

Abstract: An apparatus for removing gaseous hydrocarbon fraction from a heated gas comprises a cooled air inlet to condense the hydrocarbon to viscous liquid particles. An electrostatic field established between a points array and a plate propels the particles to a moving non-conductive collector belt, from which the liquid condensate is removed by a doctor blade and deposited into a heated receiver trough. The liquid condensate is discharged from the receiver trough into a container. A method comprises passing a heated gaseous, liquid droplet-containing stream through an electrostatic field which propels the droplets to a liquid collector, and removing the liquid from the collector, and discharging the liquid into a container for disposal.
