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 -- This message was sent by Atlassian JIRA (v6.1#6144)
