Subject [jira] [Created] (HADOOP-12719) Implement lease recover in wasb file system
Date Mon, 18 Jan 2016 09:40:39 GMT
Liu Shaohui created HADOOP-12719:
------------------------------------

             Summary: 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~
