This limits heterogeneity to the declared storage types, which are treated as fungible within the target DN. It should be possible to influence or constrain the DN policy to select a particular storage. -- 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
