## What changes were proposed in this pull request? - Changed `StreamingQueryProgress.watermark` to `StreamingQueryProgress.queryTimestamps` which is a `Map[String, String]` containing the following keys: "eventTime.max", "eventTime.min", "eventTime.avg", "processingTime", "watermark". All of them UTC formatted strings. - Renamed `StreamingQuery.timestamp` to `StreamingQueryProgress.triggerTimestamp` to differentiate from `queryTimestamps`. It has the timestamp of when the trigger was started. ## How was this patch tested? Updated tests Author: Tathagata Das <tathagata.das1565@gmail.com> Closes #16258 from tdas/SPARK-18834.

When I added a visibility check for the logs column on the executors page in #14382 the method I used only ran the check on the initial DataTable creation and not subsequent page loads.

## What changes were proposed in this pull request? Instead of only keeping the minimum number of offsets around, we should keep enough information to allow us to roll back n batches and reexecute the stream starting from a given point. In particular, we should create a config in SQLConf, spark.sql.streaming.retainedBatches that defaults to 100 and ensure that we keep enough log files in the following places to roll back the specified number of batches: the offsets that are present in each batch versions of the state store the files lists stored for the FileStreamSource the metadata log stored by the FileStreamSink marmbrus zsxwing ## How was this patch tested? The following tests were added. ### StreamExecution offset metadata Test added to StreamingQuerySuite that ensures offset metadata is garbage collected according to minBatchesRetain ### CompactibleFileStreamLog Tests added in CompactibleFileStreamLogSuite to ensure that logs are purged starting before the first compaction file that proceeds the current batch id - minBatchesToRetain.

As I pointed out in https://github.com/apache/spark/pull/15620#discussion_r91829129 , it seems that the regression test is an overkill and may hit constants pool size limitation, which is a known issue and hasn't been fixed yet.

## What changes were proposed in this pull request? - Changed FileStreamSource to use new FileStreamSourceOffset rather than LongOffset. The field is named as `logOffset` to make it more clear that this is a offset in the file stream log. - Fixed bug in FileStreamSourceLog, the field endId in the FileStreamSourceLog.get(startId, endId) was not being used at all. No test caught it earlier. Only my updated tests caught it. Other minor changes - Dont use batchId in the FileStreamSource, as calling it batch id is extremely miss leading. With multiple sources, it may happen that a new batch has no new data from a file source. So offset of FileStreamSource != batchId after that batch. ## How was this patch tested? Updated unit test.

This PR has 2 key changes. One, we are building source package (aka bundle package) for SparkR which could be released on CRAN. Two, we should include in the official Spark binary distributions SparkR installed from this source package instead (which would have help/vignettes rds needed for those to work when the SparkR package is loaded in R, whereas earlier approach with devtools does not) But, because of various differences in how R performs different tasks, this PR is a fair bit more complicated. More details below. This PR also includes a few minor fixes. These are the additional steps in make-distribution; please see [here](https://github.com/apache/spark/blob/master/R/CRAN_RELEASE.md ) on what's going to a CRAN release, which is now run during make-distribution.sh. 1. package needs to be installed because the first code block in vignettes is `library(SparkR)` without lib path 2. `R CMD build` will build vignettes (this process runs Spark/SparkR code and captures outputs into pdf documentation) 3. `R CMD check` on the source package will install package and build vignettes again (this time from source packaged) - this is a key step required to release R package on CRAN (will skip tests here but tests will need to pass for CRAN release process to success - ideally, during release signoff we should install from the R source package and run tests) 4. `R CMD Install` on the source package (this is the only way to generate doc/vignettes rds files correctly, not in step # 1) (the output of this step is what we package into Spark dist and sparkr.zip) Alternatively, R CMD build should already be installing the package in a temp directory though it might just be finding this location and set it to lib.loc parameter; another approach is perhaps we could try calling `R CMD INSTALL --build pkg` instead. But in any case, despite installing the package multiple times this is relatively fast. Building vignettes takes a while though. Manually, CI.

## What changes were proposed in this pull request? Fixes a bug in the python implementation of rdd cartesian product related to batching that showed up in repeated cartesian products with seemingly random results. The root cause being multiple iterators pulling from the same stream in the wrong order because of logic that ignored batching. `CartesianDeserializer` and `PairDeserializer` were changed to implement `_load_stream_without_unbatching` and borrow the one line implementation of `load_stream` from `BatchedSerializer`. The default implementation of `_load_stream_without_unbatching` was changed to give consistent results (always an iterable) so that it could be used without additional checks. `PairDeserializer` no longer extends `CartesianDeserializer` as it was not really proper. If wanted a new common super class could be added. Both `CartesianDeserializer` and `PairDeserializer` now only extend `Serializer` (which has no `dump_stream` implementation) since they are only meant for *de*serialization. ## How was this patch tested? Additional unit tests (sourced from #14248) plus one for testing a cartesian with zip. Author: Andrew Ray <ray.andrew@gmail.com> Closes #16121 from aray/fix-cartesian.

[SPARK-18667][PYSPARK][SQL] Change the way to group row in BatchEvalPythonExec so input_file_name function can work with UDF in pyspark ## What changes were proposed in this pull request? `input_file_name` doesn't return filename when working with UDF in PySpark. An example shows the problem: from pyspark.sql.functions import * from pyspark.sql.types import * def filename(path): return path sourceFile = udf(filename, StringType()) spark.read.json("tmp.json").select(sourceFile(input_file_name())).show() +---------------------------+ |filename(input_file_name())| +---------------------------+ | | +---------------------------+ The cause of this issue is, we group rows in `BatchEvalPythonExec` for batching processing of PythonUDF. Currently we group rows first and then evaluate expressions on the rows. If the data is less than the required number of rows for a group, the iterator will be consumed to the end before the evaluation. However, once the iterator reaches the end, we will unset input filename. So the input_file_name expression can't return correct filename. This patch fixes the approach to group the batch of rows. We evaluate the expression first and then group evaluated results to batch. ## How was this patch tested? Added unit test to PySpark.
