Lin Yiqun created HDFS-9768: ------------------------------- Summary: Reuse objectMapper instance in HDFS to improve the performance Key: HDFS-9768 URL: https://issues.apache.org/jira/browse/HDFS-9768 Project: Hadoop HDFS Issue Type: Improvement Components: performance Affects Versions: 2.7.1 Reporter: Lin Yiqun Assignee: Lin Yiqun
In HDFS-9724, it have reused the ObjectMapper instance to improve the performance in {{WebHDFS}}. But in other places, it still using ObjectMapper by {{new ObjectMapper()}}. We probably need a comprehensive review across the whole codebase to look for this pattern and modify them. In MAPREDUCE-6626, YARN-4668, these jiras also work for this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
