Zach York commented on HBASE-18309:
-----------------------------------
I'm not very familiar with the jenkins structure yet, but it looks like it is
unable to pull this jar from the nexus repo.
[~stack] [~busbey] or anyone else have a clearer idea of why it isn't finding
the jar there?
The error is below:
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-compiler-plugin:3.6.1:compile (default-compile)

> There is only one thread in LogCleaner to clean oldWALs and in our big
> cluster we find this is not enough. The number of files under oldWALs reach
> the max-directory-items limit of HDFS and cause region server crash, so we
> use multi threads for LogCleaner and the crash not happened any more.
> What's more, currently there's only one thread iterating the archive
> directory, and we could use multiple threads cleaning sub directories in
> parallel to speed it up.
