Subject [jira] [Updated] (HDFS-13382) Allocator does not initialize lotSize during hdfs mover process
Date Tue, 03 Apr 2018 13:21:00 GMT

     [ https://issues.apache.org/jira/browse/HDFS-13382?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Qingxin Wu updated HDFS-13382:
------------------------------
    Description: 
Currently, when we execute 
{code:java}
hdfs mover -p /some/path
{code}
the moverThreadAllocator in org.apache.hadoop.hdfs.server.balancer.Dispatcher does not initialize lotSize
according to  _dfs.mover.moverThreads and dfs.datanode.balance.max.concurrent.moves._ 
So, when we invoke moverThreadAllocator.allocate() method, it will always return 1.
