• Type: Improvement
• Status: Open
• Priority: Major
• Resolution: Unresolved

Description

Hadoop currently treats IPv6 as unsupported. Track related smaller issues to support IPv6.

(Current case here is mainly HBase on HDFS, so any suggestions about other test cases/workload are really appreciated.)
