| # In case one needs to do log rolling on a date change, one should set the environment property |

| # For example: |
| # HBASE_ROOT_LOGGER=INFO,DRFA |
| # The reason for changing default to RFA is to avoid the boundary case of filling out disk space as |
| # DRFA doesn't put any cap on the log size. Please refer to HBase-5655 for more context. |
