Step 2: (CDH3 only) Install the CDH Security Packages

For CDH4 Users: If you are using CDH4, you can skip this step.

If you have not already installed the hadoop-0.20-sbin and hadoop-0.20-native packages, you must now install them now on every machine in the cluster where the Cloudera Manager Agent is installed:
To install the CDH3 Security Packages:
OS | Command |
---|---|
RHEL |
$ sudo yum install hadoop-0.20-sbin $ sudo yum install hadoop-0.20-native |
SLES |
$ sudo apt-get install hadoop-0.20-sbin $ sudo apt-get install hadoop-0.20-native |
Ubuntu or Debian |
$ sudo zypper install hadoop-0.20-sbin $ sudo zypper install hadoop-0.20-native |
In CDH3, the hadoop-0.20-native package is required to support secure native I/O, and it contains the libraries to improve the performance of Hadoop's compression.
The hadoop-0.20-sbin package contains two binary programs that are both installed in $HADOOP_HOME/sbin/<architecture>.
- A binary called jsvc
- A setuid binary called task-controller
For more information about the two binary programs in the hadoop-0.20-sbin package, see Appendix B - More Information about the hadoop-0.20-sbin Binary Programs in the CDH3 Security Guide.
