当我发出这个命令时：
bin/hadoop jar hadoop-examples-*.jar grep input output 'dfs[a-z.]+'
我收到这些错误：
: No such file or directoryn/../libexec/hadoop-config.sh: line 26:

/cygdrive/d/hadoop-1.2.1/bin/../libexec/hadoop-config.sh: line 80:

bin/hadoop: line 434: exec: /cygdrive/C:/Program Files/Java/jdk1.6.0_26/bin/java: cannot execute: No such file or directory
我不明白为什么会出现这些错误。
