Summary: Add a mechanism to clean up the free queue in ByteArrayManager Key: HDFS-7321 URL: https://issues.apache.org/jira/browse/HDFS-7321 Project: Hadoop HDFS Issue Type: Improvement Reporter: Tsz Wo Nicholas Sze Assignee: Tsz Wo Nicholas Sze Priority: Minor ByteArrayManager is designed to limit the number of byte arrays allocated. It also provide a mechanism for recycling arrays. It uses a free queue to store the recycled arrays internally. When the free queue size is large and there is no array allocation for a certain time period, it should gradually release the arrays for reducing the memory usage. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
