[jira] [Commented] (SPARK-25311) `SPARK_LOCAL_HOSTNAME` unsupport
IPV6 when do host checking
[ https://issues.apache.org/jira/browse/SPARK-25311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16601751#comment-16601751 ]
Xiaochen Ouyang commented on SPARK-25311:
-----------------------------------------
IPV6, IPV4 regular expression can be used to solve this problem, but `checkHost` is revoked more frequently, and there is a certain loss in performance. I don't know if anyone else has a recommended solution?
