will increase the memory and send this command via a SOCKS proxy server.
### `(command)_(subcommand)_OPTS`
It is also possible to set options on a per subcommand basis. This allows for one to create special options for particular cases. The first part of the pattern is the command being used, but all uppercase. The second part of the command is the subcommand being used. Then finally followed by the string `_OPT`.
For example, to configure `mapred distcp` to use a 2GB heap, one would use:
```bash
MAPRED_DISTCP_OPTS="-Xmx2g"
```
These options will appear *after* `HADOOP_CLIENT_OPTS` during execution and will generally take precedence.
### `HADOOP_CLASSPATH`

## Administrator Environment
There are many environment variables that impact how the system operates. By far, the most important are the series of `_OPTS` variables that control how daemons work. These variables should contain all of the relevant settings for those daemons.
In addition to the various XML files, there are two key capabilities for administrators to configure Apache Hadoop when using the Unix Shell:
More, detailed information is contained in `hadoop-env.sh` and the other env.sh files.
* Many environment variables that impact how the system operates. This guide will only highlight some key ones. There is generally more information in the various `*-env.sh` files.
Advanced administrators may wish to supplement or do some platform-specific fixes to the existing scripts. In some systems, this means copying the errant script or creating a custom build with these changes. Apache Hadoop provides the capabilities to do function overrides so that the existing code base may be changed in place without all of that work. Replacing functions is covered later under the Shell API documentation.
* Supplement or do some platform-specific changes to the existing scripts. Apache Hadoop provides the capabilities to do function overrides so that the existing code base may be changed in place without all of that work. Replacing functions is covered later under the Shell API documentation.
### `(command)_(subcommand)_OPTS`
By far, the most important are the series of `_OPTS` variables that control how daemons work. These variables should contain all of the relevant settings for those daemons.
Similar to the user commands above, all daemons will honor the `(command)_(subcommand)_OPTS` pattern. It is generally recommended that these be set in `hadoop-env.sh` to guarantee that the system will know which settings it should use on restart. Unlike user-facing subcommands, daemons will *NOT* honor `HADOOP_CLIENT_OPTS`.
In addition, daemons that run in an extra security mode also support `(command)_(subcommand)_SECURE_EXTRA_OPTS`. These options are *supplemental* to the generic `*_OPTS` and will appear after, therefore generally taking precedence.
### `(command)_(subcommand)_USER`
Apache Hadoop provides a way to do a user check per-subcommand. While this method is easily circumvented and should not be considered a security-feature, it does provide a mechanism by which to prevent accidents. For example, setting `HDFS_NAMENODE_USER=hdfs` will make the `hdfs namenode` and `hdfs --daemon start namenode` commands verify that the user running the commands are the hdfs user by checking the `USER` environment variable. This also works for non-daemons. Setting `HADOOP_DISTCP_USER=jane` will verify that `USER` is set to `jane` before being allowed to execute the `hadoop distcp` command.

* **NameNode machines** - the machines on which you run the Active and Standby NameNodes should have equivalent hardware to each other, and equivalent hardware to what would be used in a non-HA cluster.
* **Shared storage** - you will need to have a shared directory which the NameNode machines have read/write access to. Typically this is a remote filer which supports NFS and is mounted on each of the NameNode machines. Currently only a single shared edits directory is supported. Thus, the availability of the system is limited by the availability of this shared edits directory, and therefore in order to remove all single points of failure there needs to be redundancy for the shared edits directory. Specifically, multiple network paths to the storage, and redundancy in the storage itself (disk, network, and power). Beacuse of this, it is recommended that the shared storage server be a high-quality dedicated NAS appliance rather than a simple Linux server.

Note that, in an HA cluster, the Standby NameNodes also perform checkpoints of the namespace state, and thus it is not necessary to run a Secondary NameNode, CheckpointNode, or BackupNode in an HA cluster. In fact, to do so would be an error. This also allows one who is reconfiguring a non-HA-enabled HDFS cluster to be HA-enabled to reuse the hardware which they had previously dedicated to the Secondary NameNode.

When one is within a cluster, it is recommended to use the pathname of type (1) above instead of a fully qualified URI like (2). Futher, applications should not use the knowledge of the mount points and use a path like `hdfs://namenodeContainingUserDirs:port/joe/foo/bar` to refer to a file in a particular namenode. One should use `/user/joe/foo/bar` instead.
