--------------------------------------
Summary: Thousand of CLOSE_WAIT connections to HDFS Datanode
Key: DRILL-8077
URL: https://issues.apache.org/jira/browse/DRILL-8077
Project: Apache Drill
Issue Type: Bug
Components: Storage - Other
Affects Versions: 1.16.0
Reporter: Christian Pfarr
In IPv6 environments after a while drill has a lot of connections to HDFS
Datanode in CLOSE_WAIT state.
To fix this we add '-Djava.net.preferIPv4Stack=true
-Djava.net.preferIPv6Addresses=false' to our drill configuration and the
problem vanished.
