Colin Patrick McCabe updated HDFS-3440:
---------------------------------------
Attachment: number1.001.patch
> should more effectively limit stream memory consumption when reading corrupt
> edit logs
> --------------------------------------------------------------------------------------
>
> Key: HDFS-3440
> URL: https://issues.apache.org/jira/browse/HDFS-3440
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Colin Patrick McCabe
> Assignee: Colin Patrick McCabe
> Priority: Minor
> Attachments: number1.001.patch
>
>
> Currently, we do in.mark(100MB) before reading an opcode out of the edit log.
> However, this could result in us usin all of those 100 MB when reading bogus
> data, which is not what we want. It also could easily make some corrupt edit
> log files unreadable.
> We should have a stream limiter interface, that causes a clean IOException
> when we're in this situation, and does not result in huge memory consumption.
