Rushabh S Shah commented on HDFS-10372:
---------------------------------------
bq. it's up to you to decide whether to improve it as Masatake Iwasaki
suggested.
I don't think this is required.
I edited the test on my machine to create one file after one of the volume gone
bad. It is able to create the file and I can see the block on the datanode's
good volume. But I don't see any value adding it to patch.
[~iwasakims]: Let me know if you still want me to create a new file. I will
edit my patch.
> Fix for failing TestFsDatasetImpl#testCleanShutdownOfVolume
> -----------------------------------------------------------

> Key: HDFS-10372
> URL: https://issues.apache.org/jira/browse/HDFS-10372
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: test
> Affects Versions: 2.7.3
> Reporter: Rushabh S Shah

>
> TestFsDatasetImpl#testCleanShutdownOfVolume fails very often.
> We added more debug information in HDFS-10260 to find out why this test is
> failing.
> Now I think I know the root cause of failure.
> I thought that {{LocatedBlock#getLocations()}} returns an array of
> DatanodeInfo but now I realized that it returns an array of
> DatandeStorageInfo (which is subclass of DatanodeInfo).
> In the test I intended to check whether the exception contains the xfer
> address of the DatanodeInfo. Since {{DatanodeInfo#toString()}} method returns
> the xfer address, I checked whether exception contains
> {{DatanodeInfo#toString}} or not.
> But since {{LocatedBlock#getLocations()}} returned an array of
> DatanodeStorageInfo, it has storage info in the toString() implementation.
