                 URL: https://issues.apache.org/jira/browse/TEZ-3472

            Priority: Minor


Would be better if the following messages are not displayed.

Building..broccoli-babel-transpiler is opting out of caching due to a plugin 
that does not provide a caching strategy: `function (babel) {
    var t = babel.types;

    var replaceNodeWithPrecompiledTemplate = function(node, template) {
      var compiledTemplateString = "Ember.HTMLBars.template(" + 
precompile(template) + ")";

      // Prefer calling replaceWithSourceString if it is present.
      // this prevents a deprecation warning in Babel 5.6.7+.
      //
      // TODO: delete the fallback once we only support babel >= 5.6.7.
      if (node.replaceWithSourceString) {
        node.replaceWithSourceString(compiledTemplateString);
      } else {

            var msg = "Only `import hbs from 'htmlbars-inline-precompile'` is 
supported. You used: `" + usedImportStatement + "`";
            throw file.errorWithNode(node, msg);
          }

          // suppress a deprecation warning.
          //
          // TODO: delete the fallback once we only support babel >= 5.5.0.
          if (typeof this.dangerouslyRemove === 'function') {
