[jira] [Commented] (ACCUMULO-1216) reconsider using SequenceFiles
for the WAL
[ https://issues.apache.org/jira/browse/ACCUMULO-1216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13625763#comment-13625763 ]
Michael Allen commented on ACCUMULO-1216:
-----------------------------------------
Yeah, I still think putting encryption into the codec interface is shoehorning a square peg into a round hole. See ACCUMULO-958 (https://issues.apache.org/jira/secure/attachment/12577602/Improving-Crypto-Module-Interface-v1.2.pdf) for my short PDF about why that is.

> 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.
