> Key: HDFS-5283
> URL: https://issues.apache.org/jira/browse/HDFS-5283
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: snapshots
> Affects Versions: 3.0.0, 2.1.1-beta
> Reporter: Vinay
> Assignee: Vinay

> Attachments: HDFS-5283.000.patch, HDFS-5283.patch, HDFS-5283.patch,

>
> This is observed in one of our env:
> 1. A MR Job was running which has created some temporary files and was
> writing to them.
> 2. Snapshot was taken
> 3. And Job was killed and temporary files were deleted.
> 4. Namenode restarted.
> 5. After restart Namenode was in safemode waiting for blocks
> Analysis
> ---------
> 1. Since the snapshot taken also includes the temporary files which were
> open, and later original files are deleted.
> 2. UnderConstruction blocks count was taken from leases. not considered the
> UC blocks only inside snapshots
> 3. So safemode threshold count was more and NN did not come out of safemode
