niels, i'm not familiar with the native java spi. spi = service provider interface? could you let me know if this spi is part of the hadoop api? if so, which package/class?
but yes, all nodes on the cluster are using NTP to synchronize time. however, the server (which is not a part of the hadoop cluster) accessing/interfacing with the hadoop cluster cannot be assumed to be using NTP. will this still make a difference? and actually, this is the primary reason why i need to get the date/time of the hadoop cluster (need to check if the date/time of the hadooop cluster is in sync with the server).
