dhruba borthakur updated HDFS-743:
----------------------------------
Attachment: fluctuatingFileSize_0.17.txt
This patch is for 0.17
> file size is fluctuating although file is closed
> ------------------------------------------------
>
> Key: HDFS-743
> URL: https://issues.apache.org/jira/browse/HDFS-743
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: name-node
> Reporter: dhruba borthakur
> Assignee: dhruba borthakur
> Priority: Blocker
> Attachments: fluctuatingFileSize_0.17.txt
>
>
> I am seeing that the length of a file sometimes becomes zero after a namenode
> restart. These files have only one block. All the three replicas of that
> block on the datanode(s) has non-zero size. Increasing the replication factor
> of the file causes the file to show its correct non-zero length.
> I am marking this as a blocker because it is still to be investigated which
> releases it affects. I am seeing this on 0.17.x very frequently. I might have
> seen this on 0.20.x but do not have a reproducible case yet.
