Chuan Liu commented on HADOOP-12719:
------------------------------------
I am not sure lease recovery applies to WASB since it is a HDFS internal
implementation. There may be some contracts defined on the fs API that need to
be met, e.g. hflush()/hsync() need to guarantee data is persisted. I haven't
worked on this for some time. HBase on Azure is a supported feature for some
time. I think you can contact the production team in Azure to check if they
have already supported your scenario.
> Implement lease recover in wasb file system
> -------------------------------------------
>
> Key: HADOOP-12719
> URL: https://issues.apache.org/jira/browse/HADOOP-12719
> Project: Hadoop Common
> Issue Type: New Feature
> Reporter: Liu Shaohui
>
> HBase depend on the lease recovery of file system to prevent the write
> operations from the "dead" regionservers.
> After HADOOP-9629, hadoop supports Azure Storage as an alternative Hadoop
> Compatible File System. If we want to deploy HBase on Azure storage and keep
> data safety, we need to implement lease recover in wasb file system.

> I don't know much about wasb. Any suggestions about how to implements this?
> Eg, changing permission of the hlog to readonly like FSMapRUtils does?
> Thanks~
