hadoop - /usr/local/java/jdk1.8.0_40/jre/bin/bin/java: No such file or directory -


i enter command , gives error

`bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.0.jar grep input output 'dfs[a-z.]+'

bin/hadoop: line 144: /usr/local/java/jdk1.8.0_40/jre/bin/bin/java: no such file or directory`

please help.

looks you're trying set hadoop. should find java installed in machine, go to

/etc/<hadoop>/<conf>/hadoop-env.sh

and change java_home java installed.

in order know java installed, try echo $java_home (if it's set it'll show path), if not, try search it:

sudo find /usr/ -name *jdk

now i've noticed have double /bin in path, change java_home , remove redundant /bin.
