I've downloaded Apache Apex 3.5.0 along with Malhar 3.5.0.
I've successfully started the apex client and submitted the Yahoo Finance demo example to our YARN cluster (running CDH 5.10). The cluster is running and configured properly (many Spark and MR jobs are running on it).
I see the application I submitted as RUNNING in YARN as well as in the Apex cli. However when I try to connect to the Application Master I get a 404.
org.apache.hadoop.yarn.webapp.WebAppException: /: controller for default not found
I also tried directly to connect to the appMasterTrackingUrl reported by get-app-info command, and I get the same error.
I tried a couple of apex examples, and I always get the same error.
Any idea why?
It is somewhat expected. Add "/ws/v2/stram/info" to the URL path
When you connect to the App Master you need to provide the complete URL for a REST API to invoke. There is nothing to show/return for "/" so what you are seeing is expected. What are you trying to do connecting to the App Master?

I have made a flask application at my local computer in the debugging mode and it runs all fine. But when it comes to production, the website gives me 500 or internal server error, which I have no idea what the bug is. I am fairly new to flask production and this has been stopping me from moving forward for quite a few days.
My questions are:
1> in my local development environment, one could always print things out. But how can I see those prints in the production stage?
2> Do I see them through Apache2 log? Where is Apache2 log?
For production, I actually followed the tutorials from pythonprogramming.net. Youtube link is here:
https://www.youtube.com/watch?v=qZNL4Ku1UQg&list=PLQVvvaa0QuDc_owjTbIY4rbgXOFkUYOUB&index=2
To use a very simple example, if the code imports a package which wasn't installed, where can we see the errors?
Thanks in advance.
I've tried to use to use try ... except block for every flask function. Whenever there is an exception, it can be return to the front-end. But what about other errors?
I found out:
Use logging module
Read apache2 log from /var/log/apache2
Firstly, there are related posts:
GlassFish Server update center installation times out
Java EE 7 updatetool installation fails
I got my Java EE 7 SDK (Update 3) from here: http://www.oracle.com/technetwork/java/javaee/downloads/index.html
I have tried each of the solutions in the above posts and here: https://blogs.oracle.com/dipol/troubleshooting-glassfish-update-center
Including:
In the cmd prompt running set PKG_CLIENT_CONNECT_TIMEOUT=300 and set PKG_CLIENT_READ_TIMEOUT=300 before updatetool in C:\glassfish4\bin\updatetool.bat (c:\glassfish4 in my install directory - all settings were default, including install update tool...).
Set above mentioned timeout to much larger values - doesn't appear to make a difference at all, the process basically bombs immediately.
Running C:\glassfish4\bin\updatetool.bat many times.
Triple checking that I didn't somehow configure a proxy server in my sleep.
Use the update tool via the Glassfish admin console at http://localhost:4848 (seems to show no available update or add-ons, which seems odd..)
I get the following screenshot when I run C:\glassfish4\bin\updatetool.bat
I have no idea why the error would be proxy related, unless it happened to be something on their end. Interestingly, If I go directly to the URL mentioned (via Chrome) I get the following page:
What could possibly be going wrong here?
The updatetool was a commercial feature of Oracle GlassFish. Any update functionality relied on Oracle providing a site where updates could be hosted. Since Oracle GlassFish is no longer supported, this site no longer exists so the updatetool won't work any more.
Rather than downloading GlassFish from Oracle, you should download it from the official open source site, hosted on GitHub. Alternatively, if you really do need support, you could try Payara Server which is open source, and derived from GlassFish, but has support available (disclaimer: I work for Payara)
We have a back-end API on AWS stage server not live.
But I got result failed while calling it.
I tried with cordova-plugin-whitelist and cordova-plugin-certificates but got the same result.
I am not sure that is an issue from backend config or ionic.
i build spinnaker using docker-compose follow here
but it always redirect to localhost, how can i fix this.
e.g.
http://localhost:8084/auth/redirect?to=http%3A%2F%2F192.168.99.100%3A9000%2F%23%2Finfrastructure
i set the host:0.0.0.0 in spinnaker-local.yml and configured deck apache2 with proxyPreserve=On, it's not working.
where is the configuration about 'redirect'?
All containers running well but fiat gets error mesages, like this:
WARN 1 --- [ecutionAction-1] c.n.s.fiat.roles.UserRolesSyncer : [] User permission sync failed. Server status is DOWN. Trying again in 10000 ms. Cause:(Provider: DefaultServiceAccountProvider) retrofit.RetrofitError: unexpected url: front50/serviceAccounts
i'm sure set fiat false, is this matter?
thanks.
The docker-compose link project is not available anymore. That deployment type is not supported anymore.
The easiest way i suggest for people to get started quick is by using Armory Open source Minnaker. It runs on top of a K3S small cluster and contains a functional spinnaker deployment.
Great way to get started.
I tried the debian local deployment and it failed all the time.
Enjoy your CD operations.
Following the guide at https://www.openshift.com/developers/download-cartridges i wanted to try installing the CDK to see what it brings to the table. Unfortunately, I was unable to install the cartridge because of the following error:
Unexpected error: CLIENT_ERROR: Download of 'http://cdk-claytondev.rhcloud.com/archive/2ccd7a3a7762e4ebb873c0d64a247b180e0600b8/cdk.zip' exceeded Content-Length of 9728. Download aborted.
Execute rhc create-app cdk http://cdk-claytondev.rhcloud.com/manifest/2ccd7a3a7762e4ebb873c0d64a247b180e0600b8 against a local installation of OpenShift Origin. Or try to create an App throught the web console (again on a local installation, both are untested on rhcloud).
Looks like this was an issue on OpenShift Online also, which got fixed, but is still an issue on OpenShift Origin. Here is the bugzilla ticket for this issue (https://bugzilla.redhat.com/show_bug.cgi?id=1017776), I suggest you add your email address to it to be notified as they make progress against fixing it.
