|---|---|---|
| ||
install_local_hadoop downloads Hadoop, HBase, Hive, and MySql jar files from the internet. To avoid this overhead, you can download the required files into a separate directory and set the environment variable MY_LOCAL_SW_DIST to point to this directory. |
Usage
Default ports.
| Port Variable | Default Value |
|---|---|
MY_DCS_MASTER_PORT | 23400 |
MY_DCS_MASTER_INFO_PORT | 24400 |
MY_REST_SERVER_PORT | 4200 |
MY_REST_SERVER_SECURE_PORT | 4201 |
Command Options.
| Command | What It Does |
|---|---|
install_local_hadoop | Uses default ports for all services. |
install_local_hadoop -p fromDisplay | Start Hadoop with a port number range determined from the DISPLAY environment variable. |
install_local_hadoop -p rand | Start with any random port number range between 9000 and 49000. |
install_local_hadoop -p <port > | Start with the specified port number. |

Six java servers and two mysqld processes should be running.
Note:
The 'install_local_hadoop' script downloads Hadoop, HBase, Hive, and MySql jar files from the internet. To avoid this overhead, you can download the required files into a separate directory and set the environment variable MY_LOCAL_SW_DIST to point to this directory.The following options are available with 'install_local_hadoop'. Use the -p option if the default Hadoop ports are already in use on your machine:

...
If you don't specify the -p option, the following default ports are used:
MY_DCS_MASTER_PORT=23400
MY_DCS_MASTER_INFO_PORT=24400
MY_REST_SERVER_PORT=4200
MY_REST_SERVER_SECURE_PORT=4201
When this script completes, Hadoop, HBase, Hive, and MySql (used as Hive's metadata repository) have been installed and are started.
To start/stop/check Hadoop environment using Trafodion supplied scripts, you can execute ‘swstartall’ , ‘swstopall’ and ‘swstatus’, and if you need to remove the installation, execute the 'swuninstall_local_hadoop'.
Use pre-installed Hadoop
