Ashwin Agate 963f774818 Fix Swift Rate Calculation
* To find the oldest and newest quantities
  for calculating rate, Spark Data Frame
  is converted to a Spark RDD, which makes it
  easy to do a group by and sort. The syntax to pull
  the value from a map column type in an
  RDD is rdd.map_column['key'] which
  is different from dataframe.map_column.key
  which was causing  'dict' object has no attribute
  exception

* Renamed first_attempt_at_spark_test.py to
  test_first_attempt_at_spark, because all the tests
  in that file were not being run.

* Changed the pre transform and transform specs
  which were being used by test_first_attempt_at_spark
  to newer 'dimensions#field_name that was introduced
  in rocky release.

Ashwin Agate fbad704cc2 Remove service_id from pre-transform spec
Remove unused field service_id from pre-transform spec.
service_id's original purpose was identify the service
that is genarating metric, but this information should
be provided by the source, as a dimension rather
than assigning its value in pre-transform spec.

Ashwin Agate 0cf08c45c5 Cleanup pre transform and transform specs
* Removed unused fields "event_status", "event_version",
  "record_type", "mount", "device", "pod_name", "container_name"
  "app", "interface", "deployment" and "daemon_set"
   from record_store data. Now it is not required to add
  new dimension, meta or value_meta fields to record store data
  instead use special notation, e.g. "dimension#" to refer to any
  dimension field in the incoming metric.

* Refactor and eliminate need to add any new metric.dimensions
  field in multiple places e.g. add to record store and
  instance usage dataframe schema and in all generic
  aggregation components. Added a new Map type column
  called "extra_data_map" to store any new fields, in
  instance usage data format. Map type column eliminates the
  need to add new columns to instance usage data.

* Allow users to define any fields in  "meta",
  "metric.dimensions" and "metric.value_meta" fields
  for aggregation in "aggregation_group_by_list" or
  "setter_group_by_list" using "dimensions#{$field_name}"
  or "meta#{$field_name}" or "value_meta#{$field_name}"

* Updated generic aggregation components and data formats docs.

Ashwin Agate 022bd11a4d Switch to using Spark version 2.2.0
Following changes were required:

1.)
By default the pre-built distribution
for Spark 2.2.0 is compiled with Scala 2.11.
monasca-transform requires Spark compiled with
Scala 2.10 since we use spark streaming to
pull data from Kafka and the version of Kafka
is compatible with Scala 2.10.
The recommended way is to compile Spark
with Scala 2.10, but for purposes of devstack
plugin made changes to pull the required jars
from mvn directly.
(see SPARK_JARS and SPARK_JAVA_LIB variables in
settings)
All jars get moved to
<SPARK_HOME>/assembly/target/assembly/
target/scala_2.10/jars/
Note: <SPARK_HOME>/jars gets renamed
to <SPARK_HOME>/jars_original.
spark-submit defaults to assembly location
if <SPARK_HOME>/jars directory is missing.

2.) Updated start up scripts for spark
worker and spark master with a new env variable
SPARK_SCALA_VERSIOn=2.10. Also updated
PYTHONPATH variable to add new
py4j-0.10.4-src.zip file

3.) Some changes to adhere to deprecated pyspark
function calls which were removed in Spark 2.0

Ashwin Agate f99a3faf68 Fix development environment and functional tests
Changing devstack environment vagrant box and
also rename the devstack VM to 'devstack'
from 'pg-tips'

Also fixing all the tests that were broken when
they were moved from tests/unit to tests/functional
with this review
https://review.openstack.org/#/c/400237/

Update devstack README with a section called
Development workflow for monasca-transform with
steps developers can take to develop and run
tests.

Flint Calvin d8f283c378 Started adding kubernetes metrics aggregation
There is a desire to use Monasca Transform to aggregate
kubernetes metrics.  This change is a start in that
direction.  The transformation specs in the tests
folder now include some representative aggregations
of some kubernetes metrics.

This commit also includes some changes to get
first_attempt_at_spark_test.py working again
after being moved from the unit test folder to the
functional test folder.

agatea 1579d8b9e5 Reuse existing spark sql context
Prevent creating a new spark sql context object with every batch.
Profiling of java heap for the driver indicated that there is a
steady increase (~12MB over 5 days) of
org.apache.spark.sql.execution.metric.LongSQLMetricValue
and org.apache.spark.sql.execution.ui.SQLTaskMetrics with
each batch execution. These are used by the spark streaming
ui and were not being garbage collected.
See https://issues.apache.org/jira/browse/SPARK-17381
with a similar issue.
This change along with setting
spark.sql.ui.retainedExecutions to a low number in
sparks-defaults.conf will reduce gradual increase in heap
size.
Also made a change to catch unhandled MemberNotJoined exception
because of whichthe transform service thread went into
a unresponsive state.

Ashwin Agate 00b874a6b3 Two stage transformation
Breaking down the aggregation into two stages.

The first stage aggregates raw metrics frequently and is
implemented as a Spark Streaming job which
aggregates metrics at a configurable time interval
(defaults to 10 minutes) and writes the intermediate
aggregated data, or instance usage data
to new "metrics_pre_hourly" kafka topic.

The second stage is implemented
as a batch job using Spark Streaming createRDD
direct stream batch API, which is triggered by the
first stage only when first stage runs at the
top of the hour.

Also enhanced kafka offsets table to keep track
of offsets from two stages along with streaming
batch time, last time version row got updated
and revision number. By default it should keep
last 10 revisions to the offsets for each
application.

Flint Calvin c7aabb6927 Added aggregation for vm.mem.used_mb and

Flint Calvin e4ade60711 Implemented aggregation for disk.allocation. Also set the
apache download source to use the archive site to ensure that
the dependency package does not disappear.  Also brought the
vagrant environment inline with monasca-api (i.e., use the
same values for private network, add substitution for kafka
brokers ip address to the conf).  Also parameterised
dependency sources (i.e., added settings to parameterise the
maven and apache repositories for the devstack plugin).

Ashwin Agate 8f61dd95a9 monasca-transform initial commit
The monasca-transform is a new component in Monasca that
aggregates and transforms metrics.

monasca-transform is a Spark based data driven aggregation
engine which collects, groups and aggregates existing individual
Monasca metrics according to business requirements and publishes
new transformed (derived) metrics to the Monasca Kafka queue.

Since the new transformed metrics are published as any other
metric in Monasca, alarms can be set and triggered on the
transformed metric, just like any other metric.
