Datanodes shutdown gracefully by dfsadmin command. > 2. For tests, {{Datanode.shutdown()}} is called. > Cache file will not have entries of blocks restored from trash. So these blocks will not be reported back to Namenode until another directory scan happens. > So avoid reading from cache even if exists if ROLLBACK option is used. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-issues-help@hadoop.apache.org
