JVM Proxy Setup

2010-10-20T01:47:00.001-07:00

For proxy configuration, use following code in before main method:

Static{

private static final String HTTP_PROXY_HOST = "http.proxyHost";

private static final String HTTP_PROXY_PORT = "http.proxyPort";

private static final String HTTP_PROXY_USER = "http.proxyUser";

private static final String HTTP_PROXY_PASSWORD = "http.proxyPassword";

private static final String HTTP_SET_PROXY = "http.proxySet";

System.getProperties().put(HTTP_SET_PROXY, "true");

System.getProperties().put(HTTP_PROXY_HOST, “proxyservername”);

System.getProperties().put(HTTP_PROXY_PORT, “portno”);

System.getProperties().put(HTTP_PROXY_USER, <your domainUserName>);

System.getProperties().put(HTTP_PROXY_PASSWORD, <your domainPassword>);

}

You can also use following command line option:

-Dhttp.proxyHost=proxyhostURL

-Dhttp.proxyPort=proxyPortNumber

-Dhttp.proxyUser=someUserName

-Dhttp.proxyPassword=somePassword

Either of above will work for you.

    Will Work ...

Cassandra Browser - Chiton

2010-09-13T01:55:00.000-07:00

Cassandra browser chiton Installation: (Go direct to installation steps)
------------------------------------------------------

As we know Chiton is a GTK-based browser for Cassandra.

Errors Which generally encounters:
//Chiton client's bin directory copy chiton folder. to avoid

Well, for each error we need to install respective packages. But we can avoid these by using a systematic approach.

Use following steps:
----------------------
1. Install python on your system properly. (google it for binaries).
2. Now comes to dependencies, Albiet its mention in README doc but Here I'm listing it again:

* Python 2.5 or later (We already done with it)
* Twisted 8.1.0 or later
* Thrift (latest svn)     (Checkout from apache )
* PyGTK 2.14 or later        (For this see below ***)
* simplejson                    (For this see below ###)
* Telephus (http://github.com/driftx/Telephus)

[Note we'll also required zope module. download it from http://pypi.python.org/pypi/zope.interface#downloads .
change extension from ".egg" to ".zip" -> extract it -> copy zope folder to /Lib/site-packages/ . ]

Twisted 8.1.0 or later Installation:
(hmm will suggest you to google with "twisted 10.1" will provide twisted matrix's link, here installable available & not much tricky)
After installation in any directory it'll copy there "Lib" and "Script" folder.
Goto "Lib" here you find "site-packages" inside you'll find required things copy those and paste it to :

/Lib/site-packages/

Done with twisted module

Thrift installation:'
-First python must be set in path .
then go to respective directory and run following "python setup.py install" will do work for you.

Verify with /Lib/site-packages/ directory. if thrift folder is not there then chk where it is created and paste here.

Done with Thrift part.

Now Skipping PyGTK part, that I'll take after Telephus and simplejson.

simplejson installation
It's a python module can be downloaded easily.
Now it comes with ".egg" extension (Here I'll not explain its history)
Do one thing change ".egg" to ".zip" and extract it. copy module folder to

/Lib/site-packages/

Done with simplejson part.

Telephus Installation
Path has given.
Download it, extract it.
Now go to respective directory and run following "python setup.py install" will do work for you.
Verify with /Lib/site-packages/ directory.
If respective folder is not there then chk where it is created and paste here.

Done with Telephus part.

PyGTK Installation (Note this is for windows installation)
Follow these steps:
1.Download GTK+ bundle with glade (Latest and stable) from http://ftp.gnome.org/pub/GNOME/binaries/win32/glade3/
(choose latest one)
2. Run downloaded exe.
3.Download PyGTK, PyCairo and PyGObject and run them .
Done with PyGTK.
If this not work for you then go for detail help go to pygtk site and search for windows installation procedure.

Last thing to do ...
In Chiton directory copy "chiton" folder into "bin" folder

Now run following from chiton home directory.
"python bin\chiton-client"

Good Luck ... Give your feedback/inputs which can help me too.

Lucandra Error

2010-08-18T23:31:00.000-07:00

I've faced following error while testing my Lucandra application :

(Note: I've modified package declaration for Lucandra)

Problem:

And Here is the solution::::::(Works for me)

Step 1. Change partitionar:
From

org.apache.cassandra.dht.RandomPartitioner

org.apache.cassandra.dht.OrderPreservingPartitioner

Step 2.
2.1 Stop Cassandra if running
2.2 go to cassandra system keyspcae and delete all
2.3 Start Cassandra.

Thats all .

A GOOD POEM

[IF]
If you can keep your head when all about youAre losing theirs and blaming it on you,If you can trust yourself when all men doubt youBut make allowance for their doubting too,If you can wait and not be tired by waiting,Or being lied about, don't deal in lies,Or being hated, don't give way to hating,And yet don't look too good, nor talk too wise:
