Subject [jira] [Commented] (HDFS-7342) Lease Recovery doesn't happen some times
Date Thu, 20 Nov 2014 18:35:35 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7342?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14219744#comment-14219744

Ravi Prakash commented on HDFS-7342:
------------------------------------

Hi Yongjun! Sorry for the delay, but I got to thinking
1. What is special about the penultimate block that it could be COMMITTED when the last block
is COMPLETE? Could that happen to any of the preceding blocks?
2. Do other callers of finalizeINodeFileUnderConstruction have the same expectations that
internalReleaseLease did (i.e. even when the penultimate/non-last block is !COMPLETE) it should
finalize the file.

> In some cases, LeaseManager tries to recover a lease, but is not able to. HDFS-4882 describes
a possibility of that. We should fix this
