- Add support for insert, upsert, update and and delete statements.
- Add support for compute stats with mt_dop query options.
- Update impyla version in order to be able to have access to query
error text for DML queries.
- Made flake8 fixes. flake8 on this file is clean.
For every Kudu table in the databases, we make a copy and add a
'_original' suffix to the table name. The DML queries will only make
modifications to the non original table, the original table will never
be modified. The orignal tables could be used to bring the non-original
table to the inital state. Two flags were added for doing this:
--reset-databases-before-binary-search and
--reset-databases-after-binary-search.
The DML queries are generated based on the mod values passed in with the
following flag: --dml-mod-values 11 13 17. For each mod value 4 DML
queries are generated. The DML operations will touch table rows where
primary_key % mod_value = 0. So, the larger the mod value, the more rows
would be affected. The DML queries are generated in such a way that the
data for the insert, upsert, and update queries is taken from the table
with the _original suffix. The stress test generates DML queries for
only kudu databases. For example, --tpch-kudu-db=tpch_100_kudu
--tpch-db=tpch_100 --generate-dml-queries would only generate queries
for the tpch_100_kudu database.
Here's an example of a full call with the new options that runs the
stress test on the local mini cluster:
./concurrent_select.py \
--tpch-kudu-db=tpch_kudu \
--generate-dml-queries \
--dml-mod-values 11 13 17 \
--generate-compute-stats-queries \
--select-probability=0.5 \
--mem-limit-padding-pct=25 \
--mem-limit-padding-abs=50 \
--reset-databases-before-binary-search \
--reset-databases-after-binary-search

For files that have a Cloudera copyright (and no other copyright
notice), make changes to follow the ASF source file header policy here:
http://www.apache.org/legal/src-headers.html#headers
Specifically:
1) Remove the Cloudera copyright.
2) Modify NOTICE.txt according to
http://www.apache.org/legal/src-headers.html#notice
to follow that format and add a line for Cloudera.
3) Replace or add the existing ASF license text with the one given
on the website.
Much of this change was automatically generated via:
git grep -li 'Copyright.*Cloudera' > modified_files.txt
cat modified_files.txt | xargs perl -n -i -e 'print unless m#Copyright.*Cloudera#i;'
cat modified_files_txt | xargs fix_apache_license.py [1]
Some manual fixups were performed following those steps, especially when
license text was completely missing from the file.
[1] https://gist.github.com/anonymous/ff71292094362fc5c594 with minor
modification to ORIG_LICENSE to match Impala's license text.

The major changes are:
1) Collect backtrace and fatal log on crash.
2) Poll memory usage. The data is only displayed at this time.
3) Support kerberos.
4) Add random queries.
5) Generate random and TPC-H nested data on a remote cluster. The
random data generator was converted to use MR for scaling.
6) Add a cluster abstraction to run data loading for #5 on a
remote or local cluster. This also moves and consolidates some
Cloudera Manager utilities that were in the stress test.
7) Cleanup the wrappers around impyla. That stuff was getting
messy.
