If you are doing Trafodion development on a pre-existing Hadoop distribution, then do the following:
- Distribution: Use the distribution management too. For example: Apache Ambari or Cloudera Manager.
- Regular Hadoop: Use the start/stop script for each Hadoop environment.
Local Hadoop
Use the following commands to manage the Hadoop environment.
| Command | Usage |
|---|---|
swstartall | Start the complete Hadoop environment. |
swstopall | Stops the complete Hadoop environment. |
swstatus | Checks the status of the Hadoop environment. |
swuninstall_local_hadoop | Removes the Hadoop installation. |
