             Summary: Improve execution logs for REPL commands
                 Key: HIVE-16530
                 URL: https://issues.apache.org/jira/browse/HIVE-16530
             Project: Hive
          Issue Type: Sub-task
          Components: repl
    Affects Versions: 2.2.0
            Reporter: Sankar Hariappan
            Assignee: Sankar Hariappan


This is the log format that is being proposed for Hive Repl query logs

For bootstrap case:
Hive will log a message for each object as it is being bootstrapped   And it will be in the following  sequence
- Tables first (views are tables for this purpose) at at time including partitions (depth first),
followed by functions, constraints 
- The ordering is based on the ordering of listStatus API of HDFS
- For each object, a message at the beginning of the replication will be logged
- Every partition bootstrapped will be followed by a message saying the number of partitions bootstrapped so far (for the table) and the partition name
- And a message at the end of bootstrap of an object

Incremental case:
- We will have DB Name, event id and event type  will be part of the log header (for debugging/troubleshooting)
- We will have information of current event ID and total number of events to replicate for every event replicated.
