Can I change the image of the icons on my taskbar?

Solution 1

Check this: Where are the Unity Launcher .desktop files?

Open the .desktop file you want the icon changed for and there will be a

[Desktop Entry]
Version=
Name=
Comment=
Exec=
Icon=

Obviously the file name behind "Icon=" is what you need to replace. From UnityLaunchersAndDesktopFiles:

Icon field is the icon that should be used by the launcher and represents the application. All icons that are under the directory /usr/share/pixmaps don't need to have their full path specified, but their filename without the extension. For example, if the icon file is /usr/share/pixmaps/wallch.png, then the Icon field should be just 'wallch'. All other icons should have their full path specified.

Solution 2

I use alacarte to create custom launchers for programs that come without installers or launchers etc.

Simply install using sudo apt-get install alacarte or search for it in the software centre.

This program will let you edit icons and create icons for commands or script files.

Here is an answer to a similar question with a more in-depth set of instructions on using alacarte.

I am using hadoop version 2.7.0, hive version 1.1.0, HBase version hbase-0.98.14-hadoop2.

I have created a hbase table from hive successfully.

hive (Koushik)> CREATE TABLE hive_hbase_emp_test(eid int, ename string, esal double) 
              > STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
              > WITH SERDEPROPERTIES 
              > ("hbase.columns.mapping" = ":key,cfstr:enm,cfsal:esl")
              > TBLPROPERTIES ("hbase.table.name" = "hive_hbase_emp_test");
OK

But when I am trying to load the table from hive it is failing.

What's I am missing here??

Koushik Chandra over 8 years

Actually I made a mistake. I have kept hive-hbase-handler-1.2.1.jar & hive-serde-1.2.1.jar in the auxlib path, which was causing the problem. When I removed 1.2.1 version of jars and then it is working fine with hive-hbase-handler-1.1.0.jar & hive-serde-1.1.0.jar. So the problem resolved with hive version 1.1.0 only (with habse version 0.98.14 and hadoop version 2.7.0).

That make sense because hive-hbase-hbandler-1.2.1 doesn't work with Hive 1.1.0
Jon Andrews almost 7 years

Could you give some clarity on that. I didnt get that removing jars part. Iam facing the same problem
