一、刚装上hive在执行hive启动的过程中出现
[hadoop@localhost hive-0.6.0]$ hive Invalid maximum heap size: -Xmx4096m The specified size exceeds the maximum representable size. Could not create the Java virtual machine.
解决方法：
修改$HIVE_INSTALL/bin/ext/util/execHiveCmd.sh
# increase the threashold for large queries #HADOOP_HEAPSIZE=4096 HADOOP_HEAPSIZE=128
