[jira] [Created] (HDFS-5498) Improve datanode startup time
Kihwal Lee created HDFS-5498:
--------------------------------
Summary: Improve datanode startup time
Key: HDFS-5498
URL: https://issues.apache.org/jira/browse/HDFS-5498
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Kihwal Lee
Similarly to HDFS-5027, an improvement can be made for getVomeMap(). This is the phase in which ReplicaMap.is populated. But it will be even better if datanode scans only once and do both.
