Re: [QUESTION]: httpclient dependency
Hi All, I think there may be a bit of confusion. It may be true that some of Drill's dependencies now use the newer version of the library httpcomponents:httpclient. However, it looks like ES directly depends on the older flavor. We have pom file entries which exclude that old version. As a result, ES can't find the older version at run time. So, maybe two choices. 1) convince ES to use the newer version (how?), or 2 retain the older version (don't exclude it.) Would sure be nice if each storage plugin could run in its own class loader to avoid these issues. We're slowly moving in that direction.

# [DRILL-7716](https://issues.apache.org/jira/browse/DRILL-7716): Create
Format Plugin for SPSS Files
## Description
This PR adds the ability for Drill to query SPSS files.
## Documentation
# Format Plugin for SPSS (SAV) Files
This format plugin enables Apache Drill to read and query Statistical
Package for the Social Sciences (SPSS) (or Statistical Product and Service
Solutions) data files. According
to Wikipedia: [1]
SPSS is a widely used program for statistical analysis in social science.
It is also used by market researchers, health researchers, survey companies,
government, education researchers, marketing organizations, data miners, and
others. The original SPSS manual (Nie, Bent & Hull, 1970) has been described as
one of "sociology's most influential books" for allowing ordinary researchers
to do their own statistical analysis. In addition to statistical analysis, data
management (case selection, file reshaping, creating derived data) and data
documentation (a metadata dictionary is stored in the datafile) are features of
the base software.
## Configuration
To configure Drill to read SPSS files, simply add the following code to the
formats section of your file-based storage plugin. This should happen
automatically for the default
`cp`, `dfs`, and `S3` storage plugins.
Other than the file extensions, there are no variables to configure.
```json
"spss": {
"type": "spss",
"extensions": [
"sav"
]
}
```
## Data Model
SPSS only supports two data types: Numeric and Strings. Drill maps these to
`DOUBLE` and `VARCHAR` respectively. However, for some numeric columns, SPSS
maps these numbers to
text, similar to an `enum` field in Java.
For instance, a field called `Survey` might have labels as shown below:
Value
Text
1
Yes
2
No
99
No Answer
For situations like this, Drill will create two columns. In the example
above you would get a column called `Survey` which has the numeric value (1,2
or 99) as well as a column
called `Survey_value` which will map the integer to the appropriate value.
Thus, the results would look something like this:
`Survey`
`Survey_value`
1
Yes
1
Yes
1
Yes
2
No

Yes
2
No

agozhiy opened a new pull request #2066: URL: https://github.com/apache/drill/pull/2066 # [DRILL-7705](https://issues.apache.org/jira/browse/DRILL-7705): Updated jQuery and Bootstrap libraries ## Description - jQuery: 3.2.1 -> 3.4.1 - Bootstrap: 3.1.1 -> 4.4.1 - Also fixed styles that were considerably broken after the update. Note: the latest version of jQuery is 3.5.0 but I had to revert it to 3.4.1 due to broken collapse mechanism (it is widely used on profile page). See https://github.com/twbs/bootstrap/issues/30553 for details. ## Documentation No new functionality. ## Testing Manually verified the Web UI, ran usual set of unit/functional tests.
