Validate Trafodion Installation
You can use sqlci (part of the base product) or trafci (requires separate install; see Trafodion Client Installation Guide) to validate your installation.
...
Assuming no errors, your installation has been successful. You can start working on your modifications.
Troubleshooting Tips
If you are not able to start up the environment or if there are problems running sqlci or trafci, then verify that the all the processes are up and running.
swstatusshould show at 6 java servers and 2 MySQL processes.sqcheckshould indicate all processes are running.
...
If problems persist please review logs:
$MY_SQROOT/sql/local_hadoop/*/log: Hadoop, HBase, and Hive logs.$MY_SQROOT/logs: Trafodion logs.
Manage Hadoop Environment
Pre-Existing Hadoop
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. |
Downloading New Source Code
You need to do the following each time you download new source code.
| Code Block | ||
|---|---|---|
| ||
cd <Trafodion source directory> source ./env.sh cd $MY_SQROOT/etc # delete ms.env, if it exists rm ms.env cd $MY_SQROOT/sql/scripts sqgen |

cd mysource/incubator-trafidion source ./env.sh cd $MY_SQROOT/etc # delete ms.env, if it exists rm ms.env cd $MY_SQROOT/sql/scripts sqgen |
