GitHub user gatorsmile opened a pull request: https://github.com/apache/spark/pull/14148 [SPARK-16482] [SQL] Describe Table Command for Tables Requiring Runtime Inferred Schema What changes were proposed in this pull request? If we create a table pointing to a parquet/json datasets without specifying the schema, describe table command does not show the schema at all. It only shows `# Schema of this table is inferred at runtime`. In 1.6, describe table does show the schema of such a table. For data source tables, to infer the schema, we need to load the data source tables at runtime. Thus, this PR calls the function `lookupRelation`. How was this patch tested? Added test cases You can merge this pull request into a Git repository by running: $ git pull https://github.com/gatorsmile/spark describeSchema Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/14148.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #14148 commit 57893bdf55146c4ecd0a6d72c69ec3d3e85b5207 Author: gatorsmileDate: 2016-07-11T22:30:11Z fix commit 6f2deb3405b119aff1c88cab19d3953a7ede0408 Author: gatorsmile Date: 2016-07-11T22:55:18Z another fix way commit d92ebcdfd7e525499e0c8b491eeab416ad12ecfd Author: gatorsmile Date: 2016-07-12T04:00:20Z another fix way --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.

Github user squito commented on the issue: https://github.com/apache/spark/pull/14079 discussed this offline with @vanzin, realized that actually with the latest design, it doesn't make sense to have so many maps inside one `BlacklistTracker` -- a lot of info is now intended to only be tied to one `TaskSet`, so I should push that info back into the `TaskSetManager` (where the old blacklist lived). I'll do that refactoring, which will hopefully clean things up.

GitHub user jkbradley opened a pull request: https://github.com/apache/spark/pull/14147 [SPARK-14812][ML][MLLIB][PYTHON] Experimental, DeveloperApi annotation audit for ML ## What changes were proposed in this pull request? General decisions to follow, except where noted: * spark.mllib, pyspark.mllib: Remove all Experimental annotations. Leave DeveloperApi annotations alone. * spark.ml, pyspark.ml ** Annotate Estimator-Model pairs of classes and companion objects the same way. ** For all algorithms marked Experimental with Since tag <= 1.6, remove Experimental annotation. ** For all algorithms marked Experimental with Since tag = 2.0, leave Experimental annotation. * DeveloperApi annotations are left alone, except where noted. * No changes to which types are sealed. Exceptions where I am leaving items Experimental in spark.ml, pyspark.ml, mainly because the items are new: * Model Summary classes * MLWriter, MLReader, MLWritable, MLReadable * Evaluator and subclasses: There is discussion of changes around evaluating multiple metrics at once for efficiency. * RFormula: Its behavior may need to change slightly to match R in edge cases. * AFTSurvivalRegression * MultilayerPerceptronClassifier DeveloperApi changes: * ml.tree.Node, ml.tree.Split, and subclasses should no longer be DeveloperApi ## How was this patch tested? N/A Note to reviewers: * spark.ml.clustering.LDA underwent significant changes (additional methods), so let me know if you want me to leave it Experimental. * Be careful to check for cases where a class should no longer be Experimental but has an Experimental method, val, or other feature. I did not find such cases, but please verify. You can merge this pull request into a Git repository by running: $ git pull https://github.com/jkbradley/spark experimental-audit Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/14147.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #14147 commit a8beb430de18db7171badea37f12d365b8006467 Author: Joseph K.
