[jira] [Created] (HBASE-20786) Table create with thousands of regions takes too long

stack created HBASE-20786:
-----------------------------

             Summary: Table create with thousands of regions takes too long
                 Key: HBASE-20786
                 URL: https://issues.apache.org/jira/browse/HBASE-20786
             Project: HBase
          Issue Type: Umbrella
          Components: Performance
            Reporter: stack


Internal testing has create of a table with 33k regions taking 18 minutes. Let me provide more info below. We have an executor with default ten threads handling the creation of the regions in HDFS which helps distribute out the load but its not enough. This cluster had >600 servers. Let me add detail.

Need to spend some time on speeding up create/assigns. Made this an umbrella issue so can pick off pieces of the problem as subtasks.
