Hadoop Error slave bash line 0 cd opt hadoop-1 1 0 libexec No such file or directory

Question

Master running on Ubuntu and Salve running on different OS. One of the Slave running on windows. In this case windows doesn't have the same path as Master HADOOP_PATH running on Ubuntu.

 In my case

Master node HADOOP_PATH : /opt/hadoop-1.1.0

Slave Node HADOOP_PATH : /opt/softwares/hadoop-1.1.0

while i'm starting Master node by,

bin$start-dfs.sh

It's throwing error:

slave: bash: line 0: cd: /opt/hadoop-1.1.0/libexec/..: No such file or directory
slave: bash: /opt/hadoop-1.1.0/bin/hadoop-daemon.sh: No such file or directory

Can someone help how to come out of this error?

Answer 1

Hi,

  In this case, it is searching the same path as master on the slave, but Salve has a different path. Create the same user for both Master and Slave node. Create same path (dir) as master on salve and then create the symbolic link for the actual path.

This issue can be solved in two ways:

1. Create the same path and then create a symbolic link from the actual path. (OR)
2. Start Salve daemons manually by  start-dfs.sh (OR)
3. bin#./hadoop-daemon.sh start datanode 

Hope it helps.
