[jira] [Created] (HBASE-20526) multithreads bulkload performance

Key Hutu created HBASE-20526:
--------------------------------

             Summary: multithreads bulkload performance
                 Key: HBASE-20526
                 URL: https://issues.apache.org/jira/browse/HBASE-20526
             Project: HBase
          Issue Type: Improvement
          Components: mapreduce
    Affects Versions: 2.0.0
            Reporter: Key Hutu
            Assignee: Key Hutu


When doing bulkload , some interactive with zookeeper to getting region key range may be cost more time.

In multithreads enviorment, the duration maybe cost 5 minute or more.

From the executor log, like 'Reading reply sessionid:0x262fb37f4a07080 , packet:: clientPath:null server ...' contents appear many times.

 

It likely to provide new method for bulkload, caching the key range outside
