[jira] [Created] (HBASE-21333) [amv2] large cluster startup is slow

stack created HBASE-21333:
-----------------------------

             Summary: [amv2] large cluster startup is slow
                 Key: HBASE-21333
                 URL: https://issues.apache.org/jira/browse/HBASE-21333
             Project: HBase
          Issue Type: Sub-task
          Components: amv2
    Affects Versions: 2.1.0
            Reporter: stack


Testing startup of cluster with 500+ nodes and .5M regions takes a few hours.

This is a 2.1.x cluster with batching disabled.

Looking at what the Master is doing, its mostly just parsing regionserver reports.

Stats to follow.
