This is because we use the same SparkEnv class for both executors and drivers, and we do not distinguish this case. In the longer term, we should separate out SparkEnv for the driver and SparkEnv for the executors.

In the extractLeftRightNodeAggregates function, the first set of rightNodeAgg values for Regression are set in line 792 as follows: rightNodeAgg(featureIndex)(2 * (numBins - 2)) = binData(shift + (2 * numBins - 1))) Then there is a loop that sets the rest of the values, as in line 809: rightNodeAgg(featureIndex)(2 * (numBins - 2 - splitIndex)) = binData(shift + (2 *(numBins - 2 - splitIndex))) + rightNodeAgg(featureIndex)(2 * (numBins - 1 - splitIndex)) But since splitIndex starts at 1, this ends up skipping a set of binData values. The changes here address this issue, for both the Regression and Classification cases.

This patch adds tooltips to clarify some points of confusion in the UI. When users mouse over some of the table headers (shuffle read, write, and input size) as well as over the "scheduler delay" metric shown for each stage, a black tool tip (see image below) pops up describing the metric in more detail. After the tooltip mechanism is added by this commit, I imagine others may want to add more tooltips for other things in the UI, but I think this is a good starting point. ![tooltip](https://cloud.githubusercontent.com/assets/1108612/3491905/994e179e-059f-11e4-92f2-c6c12d248d81.jpg) This looks scary-big but much of it is adding the bootstrap tool tip JavaScript. Also I have no idea what to put for the license in tooltip (I left it the same -- the Twitter apache header) or for JQuery (left it as nothing) -- @mateiz what's the right thing here? cc @pwendell @andrewor14 @rxin Author: Kay Ousterhout Closes #1314 from kayousterhout/tooltips and squashes the following commits: 19981b5 [Kay Ousterhout] Exclude non-licensed javascript files from style check d9ab5a9 [Kay Ousterhout] Response to Andrew's review 7752449 [Kay Ousterhout] [SPARK-2384] Add tooltips to UI. --- .rat-excludes | 2 + .../spark/ui/static/bootstrap-tooltip.js | 288 ++++++++++++++++++ .../spark/ui/static/initialize-tooltips.js | 21 ++ .../spark/ui/static/jquery-1.11.1.min.js | 4 + .../org/apache/spark/ui/static/webui.css | 5 + .../scala/org/apache/spark/ui/ToolTips.scala | 34 +++ .../scala/org/apache/spark/ui/UIUtils.scala | 32 +- .../apache/spark/ui/exec/ExecutorsPage.scala | 136 +++++---- .../apache/spark/ui/jobs/ExecutorTable.scala | 10 +- .../org/apache/spark/ui/jobs/StagePage.scala | 37 +-- .../org/apache/spark/ui/jobs/StageTable.scala | 15 +- 11 files changed, 491 insertions(+), 93 deletions(-) create mode 100644 core/src/main/resources/org/apache/spark/ui/static/bootstrap-tooltip.js create mode 100644 core/src/main/resources/org/apache/spark/ui/static/initialize-tooltips.js create mode 100644 core/src/main/resources/org/apache/spark/ui/static/jquery-1.11.1.min.js create mode 100644 core/src/main/scala/org/apache/spark/ui/ToolTips.scala diff --git a/.rat-excludes b/.rat-excludes index 796c32a80896c..372bc2587ccc3 100644 --- a/.rat-excludes +++ b/.rat-excludes @@ -22,6 +22,8 @@ slaves spark-env.sh spark-env.sh.template log4j-defaults.properties +bootstrap-tooltip.js +jquery-1.11.1.min.js sorttable.js .*txt .*json diff --git a/core/src/main/resources/org/apache/spark/ui/static/bootstrap-tooltip.js b/core/src/main/resources/org/apache/spark/ui/static/bootstrap-tooltip.js new file mode 100644 index 0000000000000..2934181c1006a --- /dev/null +++ b/core/src/main/resources/org/apache/spark/ui/static/bootstrap-tooltip.js @@ -0,0 +1,288 @@ +/* =========================================================== + * bootstrap-tooltip.js v2.2.2 + * http://twitter.github.com/bootstrap/javascript.html#tooltips + * Inspired by the original jQuery.tipsy by Jason Frame + * =========================================================== + * Copyright 2012 Twitter, Inc. + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + * ========================================================== */ + + +!function ($) { + + "use strict"; // jshint ;_; + + + /* TOOLTIP PUBLIC CLASS DEFINITION + * =============================== */ + + var Tooltip = function (element, options) { + this.init('tooltip', element, options) + } + + Tooltip.prototype = { + + constructor: Tooltip + + , init: function (type, element, options) { + var eventIn + , eventOut + + this.type = type + this.$element = $(element) + this.options = this.getOptions(options) + this.enabled = true + + if (this.options.trigger == 'click') { + this.$element.on('click.' + this.type, this.options.selector, $.proxy(this.toggle, this)) + } else if (this.options.trigger != 'manual') { + eventIn = this.options.trigger == 'hover' ?
