------------------------------------------

             Summary: minor corrections to 1.5 documentation regarding WAL
                 Key: ACCUMULO-2223
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2223
             Project: Accumulo
          Issue Type: Improvement
    Affects Versions: 1.5.0, 1.5.1, 1.6.0, 1.6.1, 1.7.0
            Reporter: Arshak Navruzyan
            Assignee: Arshak Navruzyan
            Priority: Minor
             Fix For: 1.5.1


A few paragraphs in the documentation suggest that the WAL is created locally and only copied to HDFS for/during recovery. 

2.8. Fault-Tolerance
The Master will coordinate the copying of write-ahead logs to HDFS so the logs are available to all tablet servers.

11.10. Recovery
Recovery is performed by asking the loggers to copy their write-ahead logs into HDFS. As the logs are copied, they are also sorted, so that tablets can easily find their missing updates. The copy/sort status of each file is displayed on Accumulo monitor status page.
