Start/Stop HttpFS
|
||||||
-----------------
|
-----------------
|
||||||
|
|

To start/stop HttpFS use HttpFS's sbin/httpfs.sh script. For example:
|
To start/stop HttpFS, use `hdfs --daemon start|stop httpfs`. For example:
|
||||||
|
|
||||||
$ sbin/httpfs.sh start
|
hadoop-${project.version} $ hdfs --daemon start httpfs
|
||||||
|
|
||||||
NOTE: Invoking the script without any parameters list all possible parameters (start, stop, run, etc.). The `httpfs.sh` script is a wrapper for Tomcat's `catalina.sh` script that sets the environment variables and Java System properties required to run HttpFS server.
|
NOTE: The script `httpfs.sh` is deprecated. It is now just a wrapper of

`hdfs httpfs`.

Embedded Tomcat Configuration
|

-----------------------------
|
|

|

To configure the embedded Tomcat go to the `tomcat/conf`.
|
|
||||||
|
|
||||||
HttpFS preconfigures the HTTP and Admin ports in Tomcat's `server.xml` to 14000 and 14001.
|
|
||||||
|
|
||||||
Tomcat logs are also preconfigured to go to HttpFS's `logs/` directory.
|
|
||||||
|
|
||||||
HttpFS default value for the maxHttpHeaderSize parameter in Tomcat's `server.xml` is set to 65536 by default.
|
|
||||||
|
|
||||||
The following environment variables (which can be set in HttpFS's `etc/hadoop/httpfs-env.sh` script) can be used to alter those values:
|
|
||||||
|
|
||||||
* HTTPFS\_HTTP\_PORT
|
|
||||||
|
|
||||||
* HTTPFS\_ADMIN\_PORT
|

To configure HttpFS to work over SSL edit the [httpfs-env.sh](#httpfs-env.sh) script in the configuration directory setting the [HTTPFS\_SSL\_ENABLED](#HTTPFS_SSL_ENABLED) to [true](#true).
|
Enable SSL in `etc/hadoop/httpfs-site.xml`:
|
||||||
|
|
||||||
In addition, the following 2 properties may be defined (shown with default values):
|
```xml
|

</property>
|

```
|
||||||
|
|
||||||
* HTTPFS\_SSL\_KEYSTORE\_FILE=$HOME/.keystore

Configure `etc/hadoop/ssl-server.xml` with proper values, for example:

|
|
||||||
* HTTPFS\_SSL\_KEYSTORE\_PASS=password
|
```xml
