Somehow, in the long chain of shell variable fiddling that creates the command line in bin/daemon.sh, there is a small mistake. The command line for tasktracker comes out (shorn of many other items) with two memory allocation requests:
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java --Xmx1000m -Xmx512m org.apache.hadoop.mapred.TaskTracker This is in Cloudera CH3, but is probably in regular 0.20. -- Lance Norskog [email protected]
