Add the support for the sparklens in spark-3.0.0 and later version of spark with scala-2.12 #63

SaurabhChawla100 · 2021-03-19T17:13:07Z

In spark 3.0.0 there are lots of changes done by the community , so creating this improvement PR to make the sparklens work with spark 3.0.0 / new version of spark and scala-2.12.

I have made code change and also tested the same .please find the output

./bin/spark-shell --jars file:///tmp//src/opensrc/sparklens/target/scala-2.12/sparklens_2.12-0.4.0.jar --conf spark.extraListeners=com.qubole.sparklens.QuboleJobListener --conf spark.eventLog.enabled=true

 OneCoreComputeHours: Measure of total compute power available from cluster. One core in the executor, running
                      for one hour, counts as one OneCoreComputeHour. Executors with 4 cores, will have 4 times
                      the OneCoreComputeHours compared to one with just one core. Similarly, one core executor
                      running for 4 hours will OnCoreComputeHours equal to 4 core executor running for 1 hour.

 NOTE: 1) Model error could be large when auto-scaling is enabled.

PRatio:        Number of tasks in stage divided by number of cores. Represents degree of
               parallelism in the stage
TaskSkew:      Duration of largest task in stage divided by duration of median task.
               Represents degree of skew in the stage
TaskStageSkew: Duration of largest task in stage divided by total duration of the stage.
               Represents the impact of the largest task on stage time.
OIRatio:       Output to input ration. Total output of the stage (results + shuffle write)
               divided by total input (input data + shuffle read)

These metrics below represent distribution of time within the stage

ShuffleWrite:  Amount of time spent in shuffle writes across all tasks in the given
               stage as a percentage
ReadFetch:     Amount of time spent in shuffle read across all tasks in the given
               stage as a percentage
GC:            Amount of time spent in GC across all tasks in the given stage as a
               percentage

If the stage contributes large percentage to overall application time, we could look into
these metrics to check which part (Shuffle write, read fetch or GC is responsible)```

@SaurabhChawla100 Should we have a separate branch for Spark 3.0 instead?

I have created a new branch for Spark 3.0. If you think its better to have a separate branch please raise this against - https://github.com/qubole/sparklens/tree/SPARK30

@mayurdb - I have changed the merge branch to SPARK30.
But I think it's better to have branch2.x and we should merge the SPARK30 to master.

How did you run the sbt compile. I have updated the resolver URL to the one mentioned above. I still am getting unresolved dependency error

sbt.ResolveException: unresolved dependency: com.eed3si9n#sbt-assembly;0.12.0: not found [error] unresolved dependency: org.spark-packages#sbt-spark-package;0.2.4: not found

my project/plugin.sbt is

`addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.12.0")

resolvers += "Spark Package Main Repo" at "https://repos.spark-packages.org/"
