Subject [jira] [Updated] (HDFS-9173) Erasure Coding: Lease recovery for striped file
Date Fri, 18 Dec 2015 19:18:46 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9173?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jing Zhao updated HDFS-9173:
----------------------------
    Attachment: HDFS-9173.09.patch

Yes, the current {{getSafeLength}} implementation depends on the assumption that the parity
chunks are only generated based on the full stripe. We need to update the whole mechanism
after supporting hflush. That requires additional metadata and maybe new protocol. So currently
I just added a new TODO to the {{getSafeLength}} method.

The new patch also fixes the findbug warning.
