No, Hadoop was started at Yahoo! by Doug Cutting, the original author of Lucene. Hadoop was based on Google's published papers on the Google File System (GFS) and MapReduce. The later project, HBase, was a direct carbon copy of Google's BigTable paper. By the time Hadoop reached maturity, Google had mostly moved onto newer technologies such as Colossus and Megastore, and mostly doesn't use MapReduce anymore. To my knowledge, Google has never used Hadoop internally, although you can lease a hosted version of Hadoop on Google Cloud Platform.
