Vihang Karajgaonkar commented on HIVE-14165:
Thanks for the patch [~stakiar]. It seems like the previous implementation was
ignoring zero length files for computing the splits. While
FileInputFormat.getSplit() creates an empty Split for the zero length files. I
am not sure how it impacts the execution, may be worth while to test. Also, if
needed may be you can ignore the empty splits before adding them to
{{FetchInputFormatSplit[] inputSplit}}

I agree we shouldn't make backwards incompatible changes to Hive. Let me know what you think of the RB. There are some alternatives to this approach though: * The file listing could be done in the background, by a dedicated thread * Listing could be done eagerly rather than lazily so that the file listing does not block the fetch operator This would offer a good speedup, but would require the same amount of metadata operations to S3. > Remove Hive file listing during split computation > - > > Key: HIVE-14165 > URL: https://issues.apache.org/jira/browse/HIVE-14165 > Project: Hive > Issue Type: Sub-task >Affects Versions: 2.1.0 >Reporter: Abdullah Yousufi >Assignee: Sahil Takiar > Attachments: HIVE-14165.02.patch, HIVE-14165.03.patch, > HIVE-14165.04.patch, HIVE-14165.05.patch, HIVE-14165.06.patch, > HIVE-14165.patch > > > The Hive side listing in FetchOperator.java is unnecessary, since Hadoop's > FileInputFormat.java will list the files during split computation anyway to > determine their size.

WRT the InputFormat issue, my feeling is that we should stray away from backwards-incompatible changes. Is there no way we can avoid the backwards-incompatible change, but still avoid the unnecessary list? I will be able to provide more targeted feedback once the RB submission has been updated. > Remove Hive file listing during split computation > - > > Key: HIVE-14165 > URL: https://issues.apache.org/jira/browse/HIVE-14165 > Project: Hive > Issue Type: Sub-task >Affects Versions: 2.1.0 >Reporter: Abdullah Yousufi >Assignee: Sahil Takiar > Attachments: HIVE-14165.02.patch, HIVE-14165.03.patch, > HIVE-14165.04.patch, HIVE-14165.05.patch, HIVE-14165.06.patch, > HIVE-14165.patch > > > The Hive side listing in FetchOperator.java is unnecessary, since Hadoop's > FileInputFormat.java will list the files during split computation anyway to > determine their size.

-
Assigning to myself as [~ayousufi] is no longer working on this issue.
I played around with this patch and found a similar speedup for a simple
{{select * from s3_partitioned_table}} query where {{s3_partitioned_table}} has
500 partitions all stored on S3 (each partition contains a CSV file of ~80 KB
in size). Performance improves by about 2x.
The only problem I see with this patch is that it is technically a backwards
incompatible change. Hive allows any custom {{InputFormat}} to be registered
for a table, or for a partition. Before this patch, Hive guaranteed that the
{{Path}} set in {{mapred.input.dir}} would always exist, and would always
contain files of non-zero length. After this patch, the given {{Path}} may not
exist, or may just be empty. This patch adds handling for {{FileInputFormat}}s,
but given that a user can register any custom {{InputFormat}} with a table its
possible some user queries may break.
I'm not sure how much of an issue this is, technically the {{InputFormat}} API
makes no claim about whether a given {{Path}} should exist or should not be
empty.
Also need to add some tests for this patch.

Abdullah Yousufi commented on HIVE-14165:
-
I believe when Hive calls getSplits() it's actually using
{code}org.apache.hadoop.mapred.FileInputFormat{code}. And is the updated
listStatus faster in the non-recursive case as well? Because if not, I think it
doesn't make sense to pass in the recursive flag as true since Hive is only
interested in the files in the top level of the path, since it currently calls
getSplits() for each partition.
However, if Hive were changed to call getSplits() on the root directory in the
partitioned case, then the listStatus(recursive) would make sense. I decided
against this change because I was not sure how to best resolve partition
elimination. For example if the query selects a single partition from a table,
then doing the listStatus(recursive) on the root directory would be slower than
just doing a listStatus on the single partition.
Also, Qubole mentions the following, which may be something to pursue in the
future.
{code}
"we modified split computation to invoke listing at the level of the parent
directory. This call returns all files (and their sizes) in all subdirectories
in blocks of 1000. Some subdirectories and files may not be of interest to
job/query e.g. partition elimination may be eliminated some of them. We take
advantage of the fact that file listing is in lexicographic order and perform a
modified merge join of the list of files and list of directories of interest."
{code}
When you mentioned earlier that Hadoop grabs 5000 objects at a time, is that
including files in subdirectories?

which {{FileInputFormat}} are you using? If it is
{{org.apache.hadoop.mapreduce.lib.input.FileInputFormat}} we could look at
switching that to the {{listStatus(recursive)}} and pickup the HADOOP-13208
speedup?

> The Hive side listing in FetchOperator.java is unnecessary, since Hadoop's
> FileInputFormat.java will list the files during split computation anyway to
> determine their size. One way to remove this is to catch the
> InvalidInputFormat exception thrown by FileInputFormat#getSplits() on the
> Hive side instead of doing the file listing beforehand.
> For S3 select queries on partitioned tables, this results in a 2x speedup.
