我正在用 4 个奴隶启动我的 hadoop，除了一台机器外，一切正常。我以完全相同的方式创建了它们。

运行 ./start-all.sh 时收到的错误是：

xxxxx: starting tasktracker, logging to /xxxxx/xxxxx/hadoop/logs/hadoop-xxxxx-tasktracker-xxxxx.out
xxxxx: /xxxxx/xxxxx/hadoop/hadoop-0.20/bin/hadoop: line 413:  7012 Aborted                 nohup $_JAVA_EXEC -Dproc_$COMMAND $JAVA_HEAP_MAX $HADOOP_OPTS -classpath "$CLASSPATH" $CLASS "$@" >"$_HADOOP_DAEMON_OUT" 2>&1 </dev/null

我不确定这个问题有人可以帮我吗？我以完全相同的方式创建了奴隶。堆设置为 1GB。太感谢了 ！

您在本机代码中看到整数溢出或整数除以零（SIGFPE由FPE_INTDIV. 引起）

该线程建议添加-XX:-UseCompressedOops到 jvm 启动标志可能会有所帮助。

该线程表明您的（linux）内核太旧：尝试升级到更新版本。
