[queston] Hou to get more info on exception.

[gsvgit]

How can I get more information about exceptions presented below?

An exception of type 'System.IO.FileNotFoundException' occurred in MBrace.Core.dll but was not handled in user code

Additional information: /mbraceassemblies/RNA.Search-0.0.0.0-qtjfk5n3jb73yfs87r6baw5h7qxjv.vgb

An exception of type 'MBrace.Core.FaultException' occurred in MBrace.Runtime.dll but was not handled in user code

Additional information: Work item 528b8aa3-94ac-400d-98ed-8906ca4bb82b given up after it faulted 1 times.

Could you please provide us with a detailed reproduction of those errors?

[gsvgit]

I use clone of Azure starter kit (commit 755d7492f6cb03442bc085e6caa96934785dbef8) for cluster configuration.

Configured cluser used in compiled code.
Project runtime: .NET 4.5
Installed packages: packages.txt
At the current time I can not provide small example of code. All simple exaples work good. You can find full project here. Code for claster placed in RNA.Search.fs ln 75

Seems, that problems may be related with dependent libraries, but I have no ideas how to get more information.

If any more specific information is necessary please contact me.

Try calling cluster.Reset() with all optional parameters set to true. You will have to re-provision your worker nodes from scratch after that.

Now I get System.IO.FileNotFoundException on cloud computation creation.
Exception message:

/mbraceassemblies/RNGLRParser-0.0.0.0-qqrjdgxba94hfdjv4x2ebap7mb7u3.vgb

Any ideas?

[eiriktsarpalis]

I would need reproduction steps in order to trace the bug, if there is one.

It is difficult for us to debug external code without a minimal reproduction sample.
A different approach is to package your code as a zip file (.exe, .dlls etc) and let
mbrace externally handle the distribution. For more details about this technique check this
https://github.com/mbraceproject/MBrace.StarterKit/blob/master/HandsOnTutorial/examples/200-launching-python-example.fsx

[gsvgit]

Thanks. I'll try to use manual binaries packaging.
Steps for reproduction are presented below.

1. git clone --recursive https://github.com/YaccConstructor/YaccConstructor.git -b min_for_azure_problem
2. Insatll \lib\Pex\pex.academic.x86.msi
3. Install Visual FSharp Tools 3.0 (available here)
4. Run build.cmd to perform initial build.
5. Configure cluster with MBrace Azure starter kit. All settings are default.
6. Open \YaccConstructor\src\YC.Bio.sln
7. Set bio\RNA.Search as startup project
8. Set build mode to Release
9. Open bio\RNA.Search\RNA.Search.fs
10. Go to line 78 and set myStorageConnectionString and myServiceBusConnectionString to appropriate value
11. Run it
12. Exception occurse on cloud computation creation on line 90.

If something does not work in build, please contact me. Unfortunately build is a challenge.

@palladin @gsvgit is this still occurring?
