Following screen shots include a quick flow on how it works.


1) Click connect to cluster on right hand side panel. Give connection URL and credentials (if there is any) to connect.

eg: URL = localhost:9160,  or  10.100.3.234:

2) After a Successful connection you will be directed to keyspace listing page. Which will include Keyspaces and clickable column family names. Click on a Column Family to Explore data.




3) Row view Page.
After clicking the column family you have landed in the row view page. It includes rows of your column family and a slice of column data as a summary.

You can search, paginate or change no of items to filter your data. Click "view more" to explore a single row.



4) Column family view page will list all the columns in a single row. You can filter the data with column name,value or time stamp. full numbered pagination is available.

  1. hello,
    I installed your tools,
    I have two remarks:

    1) I can not change data in my keyspaces from this tool, this tool is that just serves to display the data, and not edit or delete them?!

    2) in our project was that data in XML format, and aparament your program, he interprets the XML into HTML, so, I not show my data correctly, but they maquent lot of things.

    voila comment il affiche le XML :

    1. Hi,
      Please find the answers below.
      1) Yes. This tool is only to view /explore the data (As of the current version.)

      2) It was a bug and it has been fixed (Had to escape XML special characters to avoid swallowing xml tags). If you are in urgency to add that patch i can provide you with the steps. Or else will share the released version soon.

      Thanks

  2. I get the following error while listing rows from a column family.

    DataTables warning: JSON data from server could not be parsed. This is caused by a JSON formatting error.

    1. Have you kept the tool idle for a considerable time like 20 mints or more. Were there any error logs at the console. There is a bug that when session got timed out it does not give a proper warning. We will fix it soon. As a workaround you can login through the management console again and continue for the moment.

    2. Hi!

      Thanks for the update.

      I've got the same error as muthu.v when I'm trying to browse a CF. I'm trying to open the CF just after loging in so it's not a timeout problem.

      We are using CompositeType in our CF, don't know if it could cause the problem ?

  3. Hi, I'd like to use your GUI tool to access to the Cassandra. However, under Windows, when I run wso2server.bat, I got exception like this:

  4. Hi Shelan,

    I was looking for simple readonly tool for cassandra data access. Thanks for this information.
    However I was getting same error:

    DataTables warning: JSON data from server could not be parsed. This is caused by a JSON formatting error.

    We are storing data in JSON format for cassandra 1.0.7. I am trying with Carbon 4.0.0.

    ReplyDelete

  5. Hi all,

    JSON format error popping due to a limitation in the UI framework used. Whenever there is an exception it is not possible to send it to UI in a proper format, thus resulting this. You can have more details at the backend server log normally. Now Cassandra Explorer is a part of WSO2 BAM server. Can you try it and see if that resolves the problem. You can download it from here. http://wso2.com/products/business-activity-monitor/ . If the error persist could you please share if there are any errors logged at the console.

  8. hey I am using Cassandra 2.0.9 with CQL 3.1.1
    My problem is this tool show me the keyspaces present but not the ColumnFamilies (Tables) present in the keyspace.
    So pls help me.

    ReplyDelete

  9. Hi Shelan,
    I do see these errors whenever I start my 'defense4all' application & eventually the application stops running. I checked "cassandra.yaml" & I do see there is an entry for localhost:9160 as rpc address/port. Not sure what exactly I need to do (in cassandra) to make this work. I am able to run Cassandra successfully as foreground process.

    Error Logs:
    =======
    07:56:48,947 INFO [main][] - Host detected as down was added to retry queue: localhost(127.0.0.1):9160 me.prettyprint.cassandra.connection.CassandraHostRetryService.add(CassandraHostRetryService.java:57) [18 Sep]

    07:56:48,948 WARN [pool-1-thread-1][] - Downed localhost(127.0.0.1):9160 host still appears to be down: Unable to open transport to localhost(127.0.0.1):9160 , java.net.ConnectException: Connection refused

    thanks in advance,

  10. I figured out the solution. Hope it helps other..
    In cassandra.yaml, we MUST set start_rpc = true (for me it was false).

    I know the server has not been tested in Windows 8.1 so my issue could
    not has any solution but reading the stacktrace it seems that it could
    be a configuration question that I missed.

    Any idea or suggestion?
