Hadoop Syntax error: word unexpected (expecting ")") - hadoop

Question

sh start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
start-all.sh: 99: /home/songtian/下载/hadoop-2.6.0/sbin/../libexec/hadoop-config.sh: Syntax error: word unexpected (expecting ")")
And I open the hadoop-config.sh,but there is no error in 99.The next content is hadoop-config and there is no error in line 99.I don't know whether I understand the error of the sh start-all.sh. What should I modify.

Answer 1

The error is not with the config files but the way you run those scripts.
Correct way to run the scripts is to stay in hadoop-home and apply
To start cluster
sbin/start-all.sh
To stop cluster
sbin/stop-all.sh
Or
You can go in sbin directory and do
To start cluster
./start-all.sh
To stop cluster
./stop-all.sh

Answer 2

I solve it.I think I should install English Ubuntu 16.04 and then I reinstall Java and Hadoop.Then the hadoop works,so amazing!
