------------------------------------------
Summary: Iterative snapshot diff report can generate duplicate
records for creates and deletes
Key: HDFS-16121
URL: https://issues.apache.org/jira/browse/HDFS-16121
Project: Hadoop HDFS
Issue Type: Bug
Components: snapshots
Reporter: Srinivasu Majeti
Assignee: Shashikant Banerjee
Currently, iterative snapshot diff report first traverses the created list for
a directory diff and then the deleted list. If the deleted list size is lesser
than the created list size, the offset calculation in the respective list seems
wrong. So the next iteration of diff report generation call, it will start
iterating the already processed in the created list leading to duplicate
entries in the list.
Fix is to correct the offset calculation during the traversal of the deleted
list.
