Chapter 3: Post Installation
This chapter describes applying your license key, verifying the installation of RadiantOne, and troubleshooting.
Apply License Key
Copy your license.lic file into the <RLI_HOME>/vds_server directory (unless you copied the license key during the GUI-based install) before using RadiantOne.
Verification of Successful Install
- Check log files located at: <RLI_HOME>\logs\install\Install_
.log. See Troubleshooting for some common errors and their potential cause.
- To check if ZooKeeper is running properly in the ensemble, youcan execute the following <RLI_HOME>/bin/advanced/cluster.bat check (.sh on UNIX) on a RadiantOne node. You should see a message similar to the one below for all the servers in the ensemble.
2015 - 04 - 09 10:54:22 INFO com.rli.zookeeper.commands.ClusterCommands:? - Completed check with 0 errors.
The results of the system checks performed during installation are saved here:
The installer reports that the network throughput requirements are insufficient to continue the install.
Virus scanners can significantly impact I/O speed and network throughput.
Disable Virus Scanner during install. Note – after install, it is recommended to avoid or limit the scanning of RadiantOne files/folders.
In the installer wizard UI you might see: Error: Cannot establish connection with ZK ensemble at
The following error can be seen when adding cluster nodes and is caused by entering invalid credentials to connect to ZooKeeper
Verify the ZooKeeper credentials you are entering.
RadiantConfigurationFactory: loading logging configuration from file /C:/radiantone/vds/config/logging/log4j2-default-console.json
Generally due to LOG4J2-673 "plugin preloading fails in shaded jar files"
These messages are related to a known issue in Log4J2 and can be ignored since they don’t impact the actual install.
In the installer wizard UI you might see a popup message that reads: Could not find any ZooKeeper server running. Please make sure you have at least one ZooKeeper running.
There is no ZooKeeper running on the target machine indicated in the URL.
Verify the ZooKeeper URL you are entering, and that ZooKeeper is running on that machine. To manually start ZooKeeper you can run: <RLI_HOME>/bin/ runZooKeeper.bat (.sh on Linux)
