I have downloaded Cassandra community edition 2.1.2 (I know its a latest development release currently hence may not be stable). The reason being newer version of cassandra-stress tool which support YAML based configuration which enables to run the tool on my desired keyspace instead of the hardcoded "Keyspace1" in current stable version.

On Windows 7 machine when trying to run cassandra-stress via command line and specifying the path to YAML file, it is always giving error due to ":" character in path starting with "C:\"

C:\Program Files\DataStax Community\apache-cassandra\tools\bin>cassandra-stress user profile=../cqlstress-musicdb.yaml ops(insert=1)

The output is

Illegal character in path at index 10: file:///C:\Program Files\DataStax Community\apache-cassandra\tools\bin\cqlstress-musicdb.yaml

I tried different options to specify the path

  • giving absolute path
  • giving absolute path in double quotes as well as single quotes
  • copy YAML in the same folder and just specify the file name
  • copy YAML in a path without spaces because when using single quote space gives the problem
  • escaping ":" using backslash
  • ignoring "C:" from the beginning and directly starting abosolute path by "/"
  • tried different sample YAML file which comes with cassandra

As a next step, I am planning to download the source code and check whats going on there, or try this out on some linux machine if I am able to get hold of one in my org, but just thought to put this question is anyone could help.

Thanks.

  • FYI, the new C* Stress in 2.1 is backwards compatible with C* 2.0. Doesn't address your problem but wanted you to know you don't have to upgrade to 2.1 to use the new stress. – phact Dec 10 '14 at 17:13

I'm not sure what's going on there exactly, but it does seem like a bug that the new cassandra-stress has such trouble with that profile path on Windows.

I was able to make the following work:

First, copy your .yaml file to a path without spaces (like c:\temp)

Then, run the stress command using the "file:///" prefix, like the following

C:\>cd "Program Files\DataStax Community\apache-cassandra\tools"
C:\Program Files\DataStax Community\apache-cassandra\tools>bin\cassandra-stress user profile=file:///c:/temp/cqlstress-example.yaml ops(insert=1)

On Windows you may have an easier time if you install into a path like c:\cassandra rather than the default under Program Files. (Avoiding all those spaces in directory names.)

This issue is still is present in the 2.1.5 edition of Datastax Community Edition for Windows. The stack is installed under e:\cassandra and it still fails :-(. Note what is not documented is that you need to give full path using syntax like so:

file:///c:/temp/cqlstress-example.yaml

Another cruel hack is to set up a local apache server, place your yaml files there and use profile path to be served from the server like so

bin\cassandra-stress user profile=http://localhost/sample.yaml ops(insert=1)
