HDFS-16911. Distcp with snapshot diff to support Ozone filesystem. (#5364) 2023-04-10 14:03:16 -07:00

HADOOP-18582. Addendum: Skip unnecessary cleanup logic in DistCp. (#5409) 
Followup to the original HADOOP-18582.

Temporary path cleanup is re-enabled for -append jobs
as these will create temporary files when creating or overwriting files.

HADOOP-16202. Enhanced openFile(): mapreduce and YARN changes. (#2584/2) 
These changes ensure that sequential files are opened with the
right read policy, and split start/end is passed in.

As well as offering opportunities for filesystem clients to
choose fetch/cache/seek policies, the settings ensure that
processing text files on an s3 bucket where the default policy
is "random" will still be processed efficiently.

This commit depends on the associated hadoop-common patch,
which must be committed first.

HADOOP-17628. Distcp contract test is really slow with ABFS and S3A; timing out. (#3240) 
This patch cuts down the size of directory trees used for
distcp contract tests against object stores, so making
them much faster against distant/slow stores.

On abfs, the test only runs with -Dscale (as was the case for s3a already),
and has the larger scale test timeout.

After every test case, the FileSystem IOStatistics are logged,
to provide information about what IO is taking place and
what it's performance is.

There are some test cases which upload files of 1+ MiB; you can
increase the size of the upload in the option
"scale.test.distcp.file.size.kb" 
Set it to zero and the large file tests are skipped.

HADOOP-16932. distcp copy calls getFileStatus() needlessly and can fail against S3 (#1936) 
Contributed by Steve Loughran.

This strips out all the -p preservation options which have already been
processed when uploading a file before deciding whether or not to query
the far end for the status of the (existing/uploaded) file to see if any
other attributes need changing.

This will avoid 404 caching-related issues in S3, wherein a newly created
file can have a 404 entry in the S3 load balancer's cache from the
probes for the file's existence prior to the upload.

It partially addresses a regression caused by HADOOP-8143,
"Change distcp to have -pb on by default" that causes a resurfacing
of HADOOP-13145, "In DistCp, prevent unnecessary getFileStatus call when
not preserving metadata"

HADOOP-16775. DistCp reuses the same temp file within the task for different files. 
Contributed by Amir Shenavandeh.

This avoids overwrite consistency issues with S3 and other stores -though
given S3's copy operation is O(data), you are still best of using -direct
when distcp-ing to it.

HDFS-13660. DistCp job fails when new data is appended in the file while the DistCp copy job is running 
This uses the length of the file known at the start of the copy to determine the amount of data to copy.

* If a file is appended to during the copy, the original bytes are copied.
* If a file is truncated during a copy, or the attempt to read the data fails with a truncated stream,
  distcp will now fail. Until now these failures were not detected.
