I try to install additional plugins in Eclipse Kepler SR2 from Help -> Install New Software menu. I select a site or type filter text, but nothing happened, the selection window remains blank. Internet works fine on my machine as well as Help -> Eclipse Market Place menu.
Solution: close eclipse, go to eclipse workspace folder and remove the following file:
.metadata/.plugins/org.eclipse.equinox.p2.ui/dialog_settings.xml
Today I installed one more PostgreSql on one more Ubuntu. That’s why I decided to memorize my steps here for quick reference.
Type in terminal:
sudo apt-get install postgresql postgresql-contrib
sudo apt-get install pgadmin3
To set password for postgres user, open psql command prompt:
sudo -u postgres psql postgres
Type command
\password postgres
type password twice when prompted and please don’t forget it 🙂
press ctrl-D to exit
The best article of Hadoop installation I found is http://codesfusion.blogspot.ru/2013/10/setup-hadoop-2x-220-on-ubuntu.html
I adopted it a little for my configuration: Ubuntu 14.04, Hadoop 2.2.0 single node, JDK 6. Not latest versions of Java and Hadoop but I had to reproduce existing production system.
My steps are:
JDK 6 and ssh:
$ sudo apt-get install oracle-java6-installer
$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java6-installer
$ sudo apt-get install ssh
Tested with Ubuntu 14.04, Eclipse Kepler SR2
Eclipse itself works fine but menus File, Edit etc. does not open and cut off.
To fix this, open eclipse.desktop file for edit. It's located at
~/.local/share/applications/eclipse.desktop
or at /usr/share/applications/eclipse.desktop
Find the line Exec=… and replace the whole line with
replace /opt/eclipse/eclipse with a path to your Eclipse.
