--------------------------------------
Status: In Progress (was: Open)
> Avoid using InetAddress.getLocalHost() when logging info messages
> -----------------------------------------------------------------

> Key: HUDI-2561
> URL: https://issues.apache.org/jira/browse/HUDI-2561
> Project: Apache Hudi

> Priority: Minor
> Labels: pull-request-available
> Original Estimate: 2h
> Remaining Estimate: 2h

> InetAddress.getLocalHost() can take up as much as 30+seconds if the network
> configurations are not done right. This might be due to local hostname IPv6
> address missing in the /etc/hosts file or the network configs slowing down
> any IPv6 name resolutions. If this API is used for logging verbose messages
> and that too in the hot code path, it can lead order of magnitude slowness in
> the overall task.
> Sample test case showing this slowness:
> TestCleaner#testBulkInsertAndCleanByVersions
> Since we can't guarantee on the right network settings for local hostname in
> all the setups, its better to avoid using InetAddress.getLocalHost() where
> all is possible, especially when verbose logging status or debug details.
>
> Here are the codes that are currently using InetAddress.getLocalHost():
> # BitCaskDiskMap (this is in the hot code path)
> # HoodieWithTimelineServer
