i am trying to install Streamsets in my mac. while i try to start the streamsets by this command: streamsets-datacollector-3.4.3/bin/streamsets dc getting following exception:
Abnormal exit: java.lang.RuntimeException: The permissions of the realm file '/usr/local/hadoop/streamsets-datacollector-3.3.1/etc/form-realm.properties' should be owner onlyCheck STDERR for more details
As the error says, the file /usr/local/hadoop/streamsets-datacollector-3.3.1/etc/form-realm.properties should be accessible to the owner only. You can set this via:
chmod 600 /usr/local/hadoop/streamsets-datacollector-3.3.1/etc/form-realm.properties

There was an error while executing VBoxManage, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

This problem was solved by downgrading the "VirtualBox" version. Try to install version 6.38.
I am working with an Alpine container and I would like to list all running services inside this container (something like service --status-all). The container is based on the Mosquitto-Image from Dockerhub.
With a little search, I have found that the openrc package must be installed. I tried to install it using apk
apk add openrc
then it returns:

I got this error when I stop my zookeeper instance and copy all data of zookeeper in other path and change dataDir=/data/zookeeper-data in zookeeper.properties.

Seems that some snapshot files under folder /opt/confluent/zookeeper/data/version-2 are corrupted or it doesn't have permission because when I use systemctl start confluent-zookeeper i got thsi error and if I start zookeeper manually I don't have this problem.
It was from systemd want to write logs in a path that is root:root and it doesn't have permission so when I used chown -R kafka:kafka dir/to/log/path and changed permission, my problem solved.
Im getting this error::
Any help would be great,thanks in advance
An error occurred while downloading the remote file. The error
message, if any, is reproduced below. Please fix this error and try
again.
SSL read: error:00000000:lib(0):func(0):reason(0), errno 104
ive changed the permission
sudo chown username:username -R ~/.vagrant.d
also, removed temp file data.
rm -rf ~/.vagrant.d/tmp/box*
download the box using the --insecure flag, something like
vagrant box add ubuntu/trusty64 --insecure
and replace ubuntu/trusty64 by the name of the box you are downloading
I am trying to run jupyter hub for multiuser mode. I installed jupyterhub from PIP.
[root#ip-of-machine hadoop]# echo $PATH
/usr/local/bin/jupyterhub-singleuser:/usr/local/bin/jupyterhub:/sbin:/bin:/usr/sbin:/usr/bin:/opt/aws/bin
When I tun jupyterhub I get an error saying
500 : Internal Server Error
Failed to start your server. Please contact admin.
I ran it as
[root#ip-of-machine hadoop]# /usr/local/bin/jupyterhub -f ./jupyterhub/jupyterhub_config.py --no-ssl
The logs contain
[I 2016-05-03 17:13:09.406 JupyterHub spawner:465] Spawning jupyterhub-singleuser --user=jupyter --port=40770 --cookie-name=jupyter-hub-token-jupyter --base-url=/user/jupyter --hub-host= --hub-prefix=/hub/ --hub-api-url=http://127.0.0.1:8081/hub/api --ip=127.0.0.1
[E 2016-05-03 17:13:09.433 JupyterHub user:237] Unhandled error starting jupyter's server: [Errno 2] No such file or directory: 'jupyterhub-singleuser'
But there is singleuser in path. I explicitly added it to path and exported.
Any clues? Thanks.
PATH should contain a list of directories containing executables that should be found, not the executables themselves.
So instead of
/usr/local/bin/jupyterhub-singleuser:/usr/local/bin/jupyterhub:/sbin:/bin:/usr/sbin:/usr/bin:/opt/aws/bin
your PATH should be:
/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/opt/aws/bin
which should find both jupyterhub and jupyterhub-singleuser.
