How to fix annoying Duplicate class error message in NetBeans 7.+

I don't know what I did, but suddenly NetBeans started to complain that some of my classes are duplicate?
To fix this issue, close NetBeans, delete NetBeans cache, start NetBeans again.

Location of the NetBeans cache is in

C:\Users\<UserName>\AppData\Local\NetBeans\Cache

How to create remote git repo from local project

1. create files/projects/etc.
2. cd into the directory and run
    git init

3. add all of your files into git
    git add *

4. commit it
    git commit -m "Initial commit"

5. for kicks, run following command to see if you have any attached remote repos. you should not see anything
    git remote

< see below "On your remote server" section >

6. Attach remote repo
    git remote add origin ssh://user@ip.add.re.ss:22/opt/git_repos/foo-project.git

7. if you mess up, run
    git remote remove origin

8. now run #5 command and you should see origin there

9. now push your local changes to repo for everyone to see
    git push -u origin master

10. after that, you can just call
    git push

On your remote server
a. sudo su -
b. cd <path_to_git_repos>
c. mkdir foo-project.git
d. cd foo-project.git
e. git init --shared=777 --bare
if you wont specify --shared=777 you wont be able to write to it due to permission issues. If you are stuck on Writing object part during your git push, that's the reason.

Apache Accumulo rFile Generation and Import

I wrote a very quick project to demonstrate how to generate Apache Accumulo rFile in HDFS in a location of your choice and then upload it into Apache Accumulo of your choice. Some configuration will be required. The project is still work in progress... but it will give you what you need if you are looking how to generate Accumulo records programmatically, store them in HDFS and later import them into your Accumulo instance.
