Feilong He created HDFS-15337: --------------------------------- Summary: Support available space choosing policy in HDFS Persistent Memory Cache Key: HDFS-15337 URL: https://issues.apache.org/jira/browse/HDFS-15337 Project: Hadoop HDFS Issue Type: Improvement Components: caching, datanode Reporter: Feilong He Assignee: Feilong He
In HDFS-13762, we introduced HDFS Persistent Memory Cache feature. In that implementation, if more than one persistent memory volume is specified by user, a simple round-robin policy is used to pick up a volume to cache data. Evidently, the large difference of volume capacity can lead to imbalance issue. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
