I am upgrading jclouds from 1.0 to 1.6. In 1.6 the classes and the methods don't match. I need to implement login to CDN and storing file to CDN.
Is there any code that already does this?
Thanks a lot
Yes, there is some sample code for you to peruse! Take a look at the Rackspace CDN example and run it against the 1.6 release.

how to monitor/log slow running queries in Apache Cassandra 2.2.X version without using any external monitoring tools? Is there is any parameter that we can set in YAML to log slow running queries? or any other approach?
Also in CASSANDRA-12403, i see they added parameter "slow_query_log_timeout_in_ms: 500" for this purpose. Can we add this parameter in Cassandra 2.2.X version's Cassandra.YAML file? or do we need to apply this patch for 2.2.X version in order to make it work?
Its a feature in a newer version, you can upgrade or apply the patch and go off of a custom build. In 2.2.x theres no support to do it by itself.
Its a bit of a long shot but you might be able to get https://github.com/smartcat-labs/cassandra-diagnostics with https://github.com/smartcat-labs/cassandra-diagnostics/blob/dev/cassandra-diagnostics-core/COREMODULES.md#slow-query-module to work. It also only supports 2.1 and 3.0 though, I dont see 2.2 there.
I need to dump data from Nutch 2.3 into a WARC file. However, i couldn't find the necessary module. Nutch 1.x had this capability. I would like to know the proper way to do it.
As you said, at the moment the WARC exporter module is not yet ported to the 2.x branch of Nutch, nevertheless porting the https://github.com/apache/nutch/blob/master/src/java/org/apache/nutch/tools/warc/WARCExporter.java module shoudln't be that hard. As a general rule the 1.x branch of Nutch still is more used and better equiped than the 2.x branch (at least for now).
The maven repo for Log4j
Could somebody tell what is the difference between these 2 apis ? I assume the one without 1.2 suffix is the latest.
Log4j-1.2-api's are bridge api's which is used for making the applications which works on log4j-1.2.xx to work using `log4j 2
More Info
log4j-1.2-api is a brige to let log4j code log to log4j2 logfile. log4j-api is you can use it api in code to log
I cant find a method since I upgraded the Azure storage dlls.
The static method I cant find is: CloudTableClient.CreateTablesFromModel
The old class:
http://msdn.microsoft.com/en-us/library/microsoft.windowsazure.storageclient.cloudtableclient_methods.aspx
This is the new class:
http://msdn.microsoft.com/en-us/library/microsoft.windowsazure.storage.table.cloudtableclient_methods.aspx
I did some searching but couldn't find a word about this being replaced or deleted.
Does anybody have an idea?
Storage client library 2.0 is quite different from the previous version and a number of methods have been removed in the newer version. This method is one of them. If you look under the remarks section on this page: http://msdn.microsoft.com/en-us/library/microsoft.windowsazure.storageclient.cloudtableclient.createtablesfrommodel.aspx, it is recommended that you not use this method.
Since these 2 versions are quite different, it is recommended that you read up the following blog posts from the storage team before upgrading your code to use the latest version:

I also wrote a blog post about migrating code from storage client library 1.7 to 2.0 which you can read here: http://gauravmantri.com/2012/11/17/storage-client-library-2-0-migrating-table-storage-code/
What's the difference between these two assemblies and when should I use each? I find that there are class name collisions between them so I imagine that I should only use one.
Example
Microsoft.WindowsAzure.Storage has Microsoft.WindowsAzure.Storage.Table.CloudTableClient
Microsoft.WindowsAzure.StorageClient has Microsoft.WindowsAzure.StorageClient.CloudTableClient
This seems very confusing. I can't imagine that Microsoft intends these to both be used in the same project.
Microsoft.WindowsAzure.Storage is version 2.0 of storage client library while Microsoft.WindowsAzure.StorageClient is the older version. There have been many changes in version 2.0 of the library (some of them are breaking). If you're starting new, I would actually recommend using 2.0 of the library as I found it more intuitive and easy to use than the older version. If you have an application which makes use of 1.7 version of the library, before you decide to upgrade, I would actually recommend reading the following blog posts by Windows Azure Storage Team:
http://blogs.msdn.com/b/windowsazurestorage/archive/2012/10/29/introducing-windows-azure-storage-client-library-2-0-for-net-and-windows-runtime.aspx

http://blogs.msdn.com/b/windowsazurestorage/archive/2012/11/06/windows-azure-storage-client-library-2-0-tables-deep-dive.aspx
However please note that there're still some components that your application might be using which has a dependency on storage client library 1.7. Windows Azure Diagnostics is one of them. So for some time you will need to use both versions. Good thing is that you can use both versions simultaneously in your project.
Hope this helps.
EDIT:
I also wrote a few blog posts about migrating code from storage client library 1.7 to 2.0 where I covered some basic scenarios. You can read those posts here:
