achilles-junit(embedded cassandra) raises 2 exceptions during junit tests run

[vrudikov]

Finished tests are marked with green in Intellij. So tests are ok. But the whole test can't finish and tries to reconnect

The first one is related to Sigar native library:

Solution:
I downloaded binary libs from here hyperic-sigar-1.6.4.zip.
Unpacked it to "root/sigar" folder and added system property initialization to the test to avoid this error

@BeforeClass
public static void init() {
    System.setProperty("org.hyperic.sigar.path", "C://sigar");
}

Anyway, this is not good, because test Another way is to try to include this library - sigar-native-deps but i can't get rid of the exception above. I think some configuration steps needed

The second one is related to datastax core:

But I found details on official Datastax Driver page. How about to mention that in Wiki? Also it will be cool to move achilles-junit configuration steps in the Wiki as separate page

[kadamvandita]

Any solution to this?

[vrudikov]

1. Sigar - no sigar-amd64-winnt.dll in java.library.path - stays the same
2. Could not load JNR C Library, native system calls through this library will not be available
   Strange but i don't receive such message since that time

[ranjankumar03]

Any workaround of the mentioned issue.?

Need to increase wait time for Cassandra server in Achilles source code

[ranjankumar03]

Where to increase this wait time? @kadamvandita

[jgmatos]

I have this problem for a long time now. Is this ever going to get solved?

[jgmatos]

@ranjankumar03 I finally figured out a workaround (not a solution for the root cause, but a way to stop the exception from appearing in the logs): I answered it in here

[doanduyhai]

The Sigar-related exception does not prevent Achilles embedded to start correctly...

[jgmatos]

@doanduyhai In my case Achilles works just fine, as I am able to perform my tests resorting to its mock services. Still, I was getting that exception in my logs.

[RaAleks]

Hi, i have the same exception UnsatisfiedLinkError, any solution?

[doanduyhai]

Guys, I think your issue is related to the Datastax java driver, some more info here: https://groups.google.com/a/lists.datastax.com/forum/#!topic/java-driver-user/ONpgXJyqTu0
