I have to install Hadoop before installing Pig package. Hadoop requires a working Java 1.6.x installation.So I tried to run the following command to install sun-java6-jdk:
$ sudo apt-get install sun-java6-jdk
but I have problems and I obtain this error when trying to install any other package
Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 968, in simulate trans.unauthenticated = self._simulate_helper(trans) File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 1092, in _simulate_helper return depends, self._cache.required_download, \ File "/usr/lib/python2.7/dist-packages/apt/cache.py", line 235, in required_download pm.get_archives(fetcher, self._list, self._records) SystemError: E:I wasn't able to locate a file for the sun-java6-bin package. This might mean you need to manually fix this package.
How to solve this problem?
Probably means that you have not (correctly) installed Hadoop, which is required for running Pig.
You can either install on a single node for testing / development and then deploy on a cluster if you have access to one.
