Hadoop的tasktracker启动失败,重编译native库
hadoop的datanode启动失败,只能启动datanode进程,而tasktracker则未能启动,查看HADOOP HOME下的hs_err_pid*文件,错误如下:
<property> <name>hadoop.native.lib</name> <value>true</value> </property>
tasktracker就能正常启动。如果还是启动失败,可以看看gcc的版本,若gcc版本低于4.1则可能是gcc的问题,升级gcc的方法,见《Redhat AS 4 成功升级最新gcc》http://blackwing.iteye.com/admin/blogs/1534642
