As the picture below dictates, there are major areas of the logical directory tree where Hadoop persists bits, config, logs and, of course, data. The following table shows what directories are used by default when installing Hortonworks Data Platform.
| Type | Directory | Notes |
|---|---|---|
| Binaries | /usr/hdp/current/SERVICENAME | previously was at /usr/lib/SERVICENAME |
| Configuration | /etc/SERVICENAME/conf | |
| Logs | /var/log/SERVICENAME |
