[jira] [Updated] (HADOOP-14748) Wasb input streams to implement
CanUnbuffer
[ https://issues.apache.org/jira/browse/HADOOP-14748?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Steve Loughran updated HADOOP-14748:
------------------------------------
Affects Version/s: 2.9.0
Priority: Minor (was: Major)
> Wasb input streams to implement CanUnbuffer
> -------------------------------------------
>
> Key: HADOOP-14748
> URL: https://issues.apache.org/jira/browse/HADOOP-14748
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 2.9.0
> Reporter: Steve Loughran
> Priority: Minor
>
> HBase relies on FileSystems implementing CanUnbuffer.unbuffer() to force input streams to free up remote connections (HBASE-9393Link). This works for HDFS, but not elsewhere.
> WASB {{BlockBlobInputStream}} can implement this by closing the stream
> in ({{closeBlobInputStream}}, so it will be re-opened elsewhere.
