[jira] [Created] (HBASE-24740) Enable journal logging for HBase snapshot operation

Sandeep Guggilam created HBASE-24740:
----------------------------------------

             Summary: Enable journal logging for HBase snapshot operation
                 Key: HBASE-24740
                 URL: https://issues.apache.org/jira/browse/HBASE-24740
             Project: HBase
          Issue Type: Improvement
            Reporter: Sandeep Guggilam
            Assignee: Sandeep Guggilam


The HBase snapshot operation contains multiple steps like actual snapshot creation, consolidate phase (reading region manifests from HDFS) , verifier phase ( validate the consolidated manifests against the actual number of regions for the table)

 

Sometimes it happens to be taking time in one of the phases and we don't know exactly which one is taking time unless we have a thread dump at the very same time. The journal logging would definitely help us give more insights into the time taken for each phase
