------------------------------------

{code}
{code}
org.apache.hadoop.fs.TestHdfsNativeCodeLoader.testNativeCodeLoaded
I don't think this one is my fault:
java.lang.AssertionError: TestNativeCodeLoader: libhadoop.so testing was
required, but libhadoop.so was not loaded. LD_LIBRARY_PATH =
${env.LD_LIBRARY_PATH}:/testptch/hadoop/hadoop-hdfs-project/hadoop-hdfs/target/native/target/usr/local/lib:/testptch/hadoop/hadoop-hdfs-project/hadoop-hdfs/../../hadoop-common-project/hadoop-common/target/native/target/usr/local/lib
{code}
Please consider this patch for inclusion into the project.
[~elgoiri] Would you mind taking a look at this related patch? This patch has
a lot of seemingly empty changes, but I removed a lot of dead white space for
check-style.
Thanks!
> Miscellaneous Improvements for FsVolumeSpi

> Key: HDFS-13958
> URL: https://issues.apache.org/jira/browse/HDFS-13958
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: datanode
> Affects Versions: 3.3.0
> Reporter: BELUGA BEHR
> Assignee: BELUGA BEHR
> Priority: Major
> Attachments: HDFS-13958.1.patch

> The work in [HDFS-13947] allowed for using {{ArrayList}} instead of
> {{LinkedList}} when scanning DataNode local directories, however the
> {{FsVolumeSpi}} implementations were still using (and forcing)
> {{LinkedList}}. I propose changing the {{FsVolumeSpi}} signatures to allow
> for {{Collection}} instead of {{LinkedList}}. Since I'm looking at the code,
> I made some small improvements and check-style fixes.
