Subject [jira] [Updated] (HDFS-4232) NN fails to write a fsimage with stale leases
Date Wed, 28 Nov 2012 22:49:58 GMT

     [ https://issues.apache.org/jira/browse/HDFS-4232?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Daryn Sharp updated HDFS-4232:
------------------------------

    Description: The reading of a fsimage will ignore leases for non-existent files, but the
writing of an image will fail if there are leases for non-existent files.  If the image contains
leases that reference a non-existent file, then the NN will fail to start, and the 2NN will
start but fail to ever write an image.  (was: The reading of a fsimage will ignore leases
for non-existent files, but the
writing of an image will fail if there are leases for non-existent files.  If
an image is written when the namesystem and lease manager are temporarily out
of sync after a delete, then the NN will fail to start, and
the 2NN will start but fail to ever write an image.)
