QUESTION
Try to use samza.apache.org/startup/hello-samza/0.7.0/ with Bash On Windows
it will run
...ANSWER
Answered 2017-Jul-15 at 04:16I would try export JAVA_HOME="/mnt/c/Program Files (x86)/Java/jdk1.8.0_102"
to set the JAVA_HOME variable in the bash shell.
Update (response to your edit):
I wouldn't recommend trying to automatically import your Windows paths to Bash on Ubuntu on Windows, because the paths have to be converted to be understood by the bash shell (\
to /
, C:\
to mnt/c/
and so on), and because not all of the tools you're probably going to reference will work on both Windows and Linux. Instead, install what you need on the Bash shell using apt-get
(you don't need to use sudo
because BUW loads in a root shell). Java is probably fine to reference as above, but most things you'll want installed separately on Ubuntu.
QUESTION
I did everything as shown in http://samza.apache.org/startup/hello-samza/0.13/ Basically, clone the repo and type "bin/grid bootstrap". However in the end I got an error message saying zookeeper not able to start as shown below, does anyone know how can I fix this problem and what else I should do to make it work?
...ANSWER
Answered 2017-Jul-17 at 08:53You are trying to execute script bin/grid bootstrap
, but in line 191 there is an error. In that line script tries to nc -w 1 localhost $PORT
.
In other words, trying to execute netcat
command from your own terminal.
Check with the command zkServer.cmd
, that zookeeper server is up and running or check that you can successful execute a netcat command.
