Ubuntu 12.04 install Kafka [error] File name too long

I'm trying to install kafka through their instructions on Ubuntu 12.04 and getting the following error

[error] File name too long

when I run

$ ./sbt package

whole error message:

[info] Building project Kafka 0.7.2 against Scala 2.8.0

I cam across this explanation saying that they file system is encrypted and need to mount another point and install from there. Not too sure how to do that, or if this is the correct procedure. Hope someone can help, Thanks.

Answer

Copy the kafka tgz file to a directory in a different filesystem.
You can list the filesytems using the df command. The directory you attempted to install kafka will probably be in the / or /home filesystem.
Then repeat the installation procedure.

As the document mentions, it's an ugly workaround.
The alternative is to re-install ubuntu without the encrypted filesystem.
