Core to this functionality is the concept of a shell profile. Shell profiles are shell snippets that can do things such as add jars to the classpath, configure Java system properties and more.
Shell profiles may be installed in either `${HADOOP_CONF_DIR}/shellprofile.d` or `${HADOOP_HOME}/libexec/shellprofile.d`. Shell profiles in the `libexec` directory are part of the base installation and cannot be overriden by the user. Shell profiles in the configuration directory may be ignored if the end user changes the configuration directory at runtime.
Shell profiles may be installed in either `${HADOOP_CONF_DIR}/shellprofile.d` or `${HADOOP_HOME}/libexec/shellprofile.d`. Shell profiles in the `libexec` directory are part of the base installation and cannot be overridden by the user. Shell profiles in the configuration directory may be ignored if the end user changes the configuration directory at runtime.
An example of a shell profile is in the libexec directory.
## Shell API
### Shell API
Apache Hadoop's shell code has a [function library](./UnixShellAPI.html) that is open for administrators and developers to use to assist in their configuration and advanced feature management. These APIs follow the standard [Apache Hadoop Interface Classification](./InterfaceClassification.html), with one addition: Replaceable.
@ -97,10 +97,8 @@ The shell code allows for core functions to be overridden. However, not all func
In order to replace a function, create a file called `hadoop-user-functions.sh` in the `${HADOOP_CONF_DIR}` directory. Simply define the new, replacement function in this file and the system will pick it up automatically. There may be as many replacement functions as needed in this file. Examples of function replacement are in the `hadoop-user-functions.sh.examples` file.
Functions that are marked Public and Stable are safe to use in shell profiles as-is. Other functions may change in a minor release.
### User-level API Access
In addition to `.hadoop-env`, which allows individual users to override `hadoop-env.sh`, user's may also use `.hadooprc`. This is called after the Apache Hadoop shell environment has been configured and allows the full set of shell API function calls.
@ -112,3 +110,84 @@ hadoop_add_classpath /some/path/custom.jar
```
would go into `.hadooprc`
### Dynamic Subcommands
Utilizing the Shell API, it is possible for third parties to add their own subcommands to the primary Hadoop shell scripts (hadoop, hdfs, mapred, yarn).
Prior to executing a subcommand, the primary scripts will check for the existence of a (scriptname)\_subcommand\_(subcommand) function. This function gets executed with the parameters set to all remaining command line arguments. For example, if the following function is defined:
```bash
function yarn_subcommand_hello
{
echo "$@"
exit $?
}
```
then executing `yarn --debug hello world I see you` will activate script debugging and call the `yarn_subcommand_hello` function as:
```bash
yarn_subcommand_hello world I see you
```
which will result in the output of:
```bash
world I see you
```
It is also possible to add the new subcommands to the usage output. The `hadoop_add_subcommand` function adds text to the usage output. Utilizing the standard HADOOP_SHELL_EXECNAME variable, we can limit which command gets our new function.
```bash
if [[ "${HADOOP_SHELL_EXECNAME}" = "yarn" ]]; then
hadoop_add_subcommand "hello" "Print some text to the screen"
fi
```
This functionality may also be use to override the built-ins. For example, defining:
```bash
function hdfs_subcommand_fetchdt
{
...
}
```
... will replace the existing `hdfs fetchdt` subcommand with a custom one.
Some key environment variables related to Dynamic Subcommands:
* HADOOP\_CLASSNAME
This is the name of the Java class to use when program execution continues.
* HADOOP\_SHELL\_EXECNAME
This is the name of the script that is being executed. It will be one of hadoop, hdfs, mapred, or yarn.
* HADOOP\_SUBCMD
This is the subcommand that was passed on the command line.
* HADOOP\_SUBCMD\_ARGS
This array contains the argument list after the Apache Hadoop common argument processing has taken place and is the same list that is passed to the subcommand function as arguments. For example, if `hadoop --debug subcmd 1 2 3` has been executed on the command line, then `${HADOOP_SUBCMD_ARGS[0]}` will be 1 and `hadoop_subcommand_subcmd` will also have $1 equal to 1. This array list MAY be modified by subcommand functions to add or delete values from the argument list for further processing.
* HADOOP\_SUBCMD\_SECURESERVICE
If this command should/will be executed as a secure daemon, set this to true.
* HADOOP\_SUBCMD\_SECUREUSER
If this command should/will be executed as a secure daemon, set the user name to be used.
* HADOOP\_SUBCMD\_SUPPORTDAEMONIZATION
If this command can be executed as a daemon, set this to true.
* HADOOP\_USER\_PARAMS
This is the full content of the command line, prior to any parsing done. It will contain flags such as `--debug`. It MAY NOT be manipulated.
The Apache Hadoop runtime facilities require functions exit if no further processing is required. For example, in the hello example above, Java and other facilities were not required so a simple `exit $?` was sufficient. However, if the function were to utilize `HADOOP_CLASSNAME`, then program execution must continue so that Java with the Apache Hadoop-specific parameters will be launched against the given Java class. Another example would be in the case of an unrecoverable error. It is the function's responsibility to print an appropriate message (preferably using the hadoop_error API call) and exit appropriately.
