----------------------------------
Summary: Change the output of DatanodeInfo in the log to the
hostname of the datanode
Key: HBASE-28775
URL: https://issues.apache.org/jira/browse/HBASE-28775
Project: HBase
Issue Type: Improvement
Components: wal
Reporter: MisterWang
Now, DatanodeInfo will be output in the print log. When we are troubleshooting
and searching for slow datanode nodes, we need to convert IP addresses to
hostnames, which is quite cumbersome.
I think the output log should has good readability, so it would be better to
output the hostname of the datanode.
