Question

How can i do a conditional row count in cassandra using hector something like below we do in RDBMS using hector thrift API:

Select count(*) from table_name where column_name = column_value

Solution 1

Take a look at this YouTube HTML5 Video Player. It might be flash related since Adobe decided not to keep updated for flash under Linux. Choose to use the HTML5 player instead of the Flash player for most videos.

Also you can try, disabling hardware acceleration in Flash by right clicking the video, and choose Settings. Or you can reinstall your flash plugin.

Solution 2

As Mitch has mentioned, YouTube usually uses Flash, so this looks like a problem with Flash. It happens in multiple browsers, so it is probably not being triggered by user-specific files that are also browser-specific.

Let's see if it's being triggered by user-specific temporary Flash files. Remove them, like this. (This tends to fix a number of Flash performance problems.)

cd; rm -r .adobe .macromedia

Run that command in a Terminal window (Ctrl+Alt+T) while no web browser is running. Then go back into a web browser afterwards to see if there is any improvement.

If that does not help, please edit your question to provide the following information:

1. If you remember (or as well as you remember): How did you install Flash?

2. The output of lsb_release -a; uname -a; dpkg -l | egrep 'flash|gnash|swf|lightspark'. This will reveal information about what Flash plugin(s) you have installed, so if the problem is the result of multiple plugins, this usually provides enough information to lead to a solution.

3. Is it any different if you try using a different user account? (If you don't have a second account on your Ubuntu system, you can use the guest account, accessible from the login screen. Or you can create a second account for testing purposes.)

Hey thanks to both of you! Ironically.. I don't have that problem anymore today.. Maybe the tweaks I did yesterday actually paid off after restarting the laptop. If the problem comes up again tomorrow I will give your suggestions a try!

Take the example of stackoverflow site. Suppose i have to count the number of answer of a particular question , how can i do that: iterate over the rows of column family or shall i maintain a counter family to count the number of answer

[abhi]

you should maintain a CF for that. Moreover its a cost effective way

[Manish Kumar]

can you suggest a effective way for this.

[abhi]

best practice will be update your cassandra counter column family counters while data is getting inserted.
