Windows installation ?

[Phil4]

I tried to install the tool but I'm using Windows as operating system.
Everything seems to be working except that no Elastic Search instance is launched.
I think it is only launched through bin/cassandra but not from bin/cassandra.bat but I didn't look further.

Here is the trace of the command "cassandra -e":

WARNING! Powershell script execution unavailable.
   Please use 'powershell Set-ExecutionPolicy Unrestricted'
   on this user-account to run cassandra with fully featured
   functionality on this platform.
Starting with legacy startup options
Starting Cassandra Server

Sorry, the cassandra.bat is not ready to run elassandra on Windows right now. However, you can probably copy the code of the -e option from bin/cassandra to the bin/cassandra.bat to activate Elasticsearch on your windows plateform.
Thanks',
Vincent.

I downloaded cassandra-2.2.6, then loaded elassandra-2.1.1-14 on top of it, and only changed the classpath/CASSANDRA_MAIN

CASSANDRA_MAIN=org.apache.cassandra.service.ElassandraDaemon

But it errors with "could not find or load main class org.apache.cassandra.service.ElassandraDaemon.

Any idea ?
Thank You

@vroyer I fixed the previous issue by redownloading the release.

Though now I'm getting:

Starting with legacy startup options
Starting Cassandra Server
{2.1.1}: Initialization Failed ...

• IllegalStateException[failed to load bundle [] due to jar hell]
  NoSuchFileException[C:\Users\admin\Desktop\elassandra-2.1.1-14\build\cla
  sses\main]

[vroyer]

Hi,
This is a classpath issue. org.apache.cassandra.service.ElassandraDaemon is the main class to launch Elassandra, but it seems that C:\Users\admin\Desktop\elassandra-2.1.1-14\build\cla sses\main does not contains it.
Thanks.

This happens when I run it on ubuntu12.04:

See Caused by: org.apache.cassandra.exceptions.ConfigurationException: Expecting URI in variable: [cassandra.config]. Please prefix the file with file:/// for local files or file:/// for remote files.
You should set CASSANDRA_CONF env variable or cassandra.config system property.

You may try to install the debian package available at http://packages.elassandra.io/deb/elassandra_2.1.1-14_all.deb

@vroyer
Another error trying to manually install the .deb file.

[ddorian]

Even this guide doesn't work with error:

Somehow it's getting the path wrong.

[vroyer]

Please use the rigth path i gave you yesterday
http://packages.elassandra.io/deb/elassandra_2.1.1-14_all.deb

[ddorian]

@vroyer As you can see here I have downloaded the right file.
While when using apt-get it uses the wrong path.

[ddorian]

@vroyer can you give me sample of cassandra.config value (absolute path) that I can use or environment variable value? I tried different options and none worked and also tried searching for samples and couldn't find any. thanks

[vroyer]

Hi,
We are checking that the packages 2.1.1-14 is correct.
In order to start elassandra, you should set and export CASSANDRA_HOME to your elassandra installation directory.
Thanks',
Vincent.

@vroyer , I have managed to patch cassandra.ps1 and set CASSANDRA_MAIN to ElassandraDaemon. Still the elassandra does not load with the following error:

{2.4.2}: Initialization Failed ...

• IllegalStateException[failed to load bundle [file:/C:/elassandra-2.4.2/modules/lang-expression/antlr4-runtime-4.5.1-1.jar, file:/C:/elassandra-2.4.2/modules/lang-expression/asm-commons-5.0.4.jar, file:/C:/elassandra-2.4.2/modules/lang-expression/lang-expression-2.4.2.jar, file:/C:/elassandra-2.4.2/modules/lang-expression/lucene-expressions-5.5.2.jar] due to jar hell]
  NoSuchFileException[C:\elassandra-2.4.2\build\classes\main]

C:\elassandra-2.4.2\build\classes\main does not exist at all, it is development folder in a class path and I am trying to launch elassandra from a tarball.

How can I start elassandra on windows?

[dukei]

Well it has started sucessfully when I created these build directories.

I have modified windows launch scripts:
#97

[DBarthe]

Windows support added with 779289e

[jsebrien]

The previous commit does not seem to be merged in 6.x version. How can we start Elassandra under windows?
