             Summary: reconsider using SequenceFiles for the WAL
                 Key: ACCUMULO-1216
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1216
             Project: Accumulo
          Issue Type: Task
          Components: tserver
    Affects Versions: 1.5.0
            Reporter: Eric Newton
            Priority: Minor


Observing the code in HBase we learned that WAL files written/flushed to HDFS would *not* present the correct file size, which made using SequenceFile for WALs problematic.  So we just write Writables.  In a sequence.

However, it would be nice to go back and use SequenceFile.

It might be possible since learning how to properly close a file.
