I didn't know how to adjust that memory parameter. However, looking in hadoop-env.sh I discovered that it was set at 1024MB:</P><P>export HADOOP_NAMENODE_INIT_HEAPSIZE="-Xms1024m"</P><P>Unfortunately, that didn't solve the problem.</P> Tue, 19 Jul 2016 13:58:39 GMT jaimecarodrigue 2016-07-19T13:58:39Z
