Question

我只是下载并安装hadoop，请参见下面的终端输出：

steven81@steven81-HP:/usr/local/hadoop-3.0.3/bin$ ls -l
total 844
-rwxr-xr-x 1 steven81 steven81 366296 6月   1 01:25 container-executor

-rwxr-xr-x 1 steven81 steven81  12840 6月   1 01:25 yarn.cmd

steven81@steven81-HP:/usr/local/hadoop-3.0.3/bin$ hadoop
hadoop: command not found

那为什么我会收到指示未找到hadoop命令的错误？

我该如何解决？

您需要编辑PATH变量以在其中包含bin目录

否则，必须从该目录完全像erl_crash_dump:0.5 Sat Jun 23 09:17:30 2018 Slogan: init terminating in do_boot ({error,{no such file or directory,asn1.app}}) System version: Erlang/OTP 20 [erts-9.3.3] [source] [64-bit] [smp:24:24] [ds:24:24:10] [async-threads:384] [hipe] [kernel-poll:true] Compiled: Tue Jun 19 22:25:03 2018 Taints: erl_tracer,zlib Atoms: 14794 Calling Thread: scheduler:2 =scheduler:1 Scheduler Sleep Info Flags: SLEEPING | TSE_SLEEPING | WAITING Scheduler Sleep Info Aux Work: Current Port: Run Queue Max Length: 0 Run Queue High Length: 0 Run Queue Normal Length: 0 Run Queue Low Length: 0 Run Queue Port Length: 0 Run Queue Flags: OUT_OF_WORK | HALFTIME_OUT_OF_WORK Current Process: =scheduler:2 Scheduler Sleep Info Flags: Scheduler Sleep Info Aux Work: THR_PRGR_LATER_OP Current Port: Run Queue Max Length: 0 Run Queue High Length: 0 Run Queue Normal Length: 0 Run Queue Low Length: 0 Run Queue Port Length: 0 Run Queue Flags: OUT_OF_WORK | HALFTIME_OUT_OF_WORK | NONEMPTY | EXEC Current Process: <0.0.0> Current Process State: Running Current Process Internal State: ACT_PRIO_NORMAL | USR_PRIO_NORMAL | PRQ_PRIO_NORMAL | ACTIVE | RUNNING | TRAP_EXIT | ON_HEAP_MSGQ Current Process Program counter: 0x00007fbd81fa59c0 (init:boot_loop/2 + 64) Current Process CP: 0x0000000000000000 (invalid)那样运行命令

一些示例将显示Failed: context.getThemeContext is not a function TypeError: context.getThemeContext is not a function at ComponentWithContext.getChildContext，它作为绝对路径转换为./hadoop

Hadoop无法运行
