21. Troubleshooting

To validate the installation, run the smoke test suite as described in Validating the Installation.

If the HBase RegionServer and Master do not start, check to see if a parenthesis in the Path variable caused a problem during setup of the services. To fix this, run the following commands from an Administrator command prompt:

 %HBASE_HOME%\bin\hbase.cmd --service master start > 
 %HBASE_HOME%\bin\master. xml 
 %HBASE_HOME%\bin\hbase.cmd --service regionserver start > 
 %HBASE_HOME%\bin\ regionserver.xml 
 %HBASE_HOME%\bin\hbase.cmd --service rest > 
 %HBASE_HOME%\bin\rest.xml 
 %HBASE_HOME%\bin\hbase.cmd --service thrift > 
 %HBASE_HOME%\bin\thrift.xml
          

Restart the HBase services.

If Flume is not starting, it could be because flumeservice.xml is missing. To fix this, navigate to %FLUME_HOME%\bin and locate the flumeagent.xml file. If the file does not exist, locate flumeservice.xml file and rename it to flumeagent.xml. After the file is renamed, go to Windows Services and restart the Flume agent service.

To help diagnose installation issues, see log file information in File Locations, Logging, and Common HDFS Commands.
