[jira] [Created] (HDFS-12390) Supporting DNS to switch mapping
Jiandan Yang created HDFS-12390:
------------------------------------
Summary: Supporting DNS to switch mapping
Key: HDFS-12390
URL: https://issues.apache.org/jira/browse/HDFS-12390
Project: Hadoop HDFS
Issue Type: New Feature
Components: hdfs, hdfs-client
Reporter: Jiandan Yang
Assignee: Jiandan Yang
As described in [HDFS-12200|https://issues.apache.org/jira/browse/HDFS-12200], ScriptBasedMapping may lead to NN cpu 100%. ScriptBasedMapping run sub_processor to get rack info of DN/Client, so we think it's a little heavy. We prepare to use TableMappingļ¼but TableMapping does not support refresh and can not reload rack info of newly added DataNodes.
So we implement it.
