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

  Note:

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.
