I am getting the error while trying to execute below block of code:
String solrUrl="http://10.52.21.4:8021/solr/";
ArrayList<String> fields = new ArrayList<String>();
CollectionAdminResponse response = ( CollectionAdminResponse ) request.process( new CloudSolrClient.Builder().withZkHost( solrUrl ).build() );
fields = ( ArrayList<String> ) response.getResponse().get( "collections" );
Anybody please help with the problem.

Has there anyway to ignore errors of google-closure JSCompiler?

I tried to compress Inputmask.js file. Here is my code to work
public class JSFileMinifyTest {
public static void main(String[] args) throws Exception {
String sourceFileName = "D:\\temp\\jquery.inputmask.bundle.js";
String outputFilename = "D:\\temp\\combined.min.js";
com.google.javascript.jscomp.Compiler.setLoggingLevel(Level.INFO);
com.google.javascript.jscomp.Compiler compiler = new com.google.javascript.jscomp.Compiler();
CompilerOptions options = new CompilerOptions();
CompilationLevel.WHITESPACE_ONLY.setOptionsForCompilationLevel(options);
options.setAggressiveVarCheck(CheckLevel.OFF);
options.setRuntimeTypeCheck(false);
options.setCheckRequires(CheckLevel.OFF);
options.setCheckProvides(CheckLevel.OFF);
options.setReserveRawExports(false);
WarningLevel.VERBOSE.setOptionsForWarningLevel(options);
// To get the complete set of externs, the logic in
// CompilerRunner.getDefaultExterns() should be used here.
SourceFile extern = SourceFile.fromCode("externs.js", "function alert(x) {}");
SourceFile jsFile = SourceFile.fromFile(sourceFileName);
compiler.compile(extern, jsFile, options);
for (JSError message : compiler.getWarnings()) {
System.err.println("Warning message: " + message.toString());
}
for (JSError message : compiler.getErrors()) {
System.err.println("Error message: " + message.toString());
}
FileWriter outputFile = new FileWriter(outputFilename);
outputFile.write(compiler.toSource());
outputFile.close();
}
}
But error occured while compressing this js file.

Has there anyways to skip syntax validations or ignore errors and continue to compress ?

The compiler by default, parses code as 'use strict'. 'static' is a reserved word in strict mode. You can either change the language mode or simply renamed the variable from 'strict' to something else.
The strict mode reserve words are documented here:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode#Paving_the_way_for_future_ECMAScript_versions

Stacking of different models (including rf, glm) in h2o (R)

I have a question regarding h2o.stackedEnsemble in R. When I try to create an ensemble from GLM models (or any other models and GLM) I get the following error:
DistributedException from localhost/127.0.0.1:54321: 'null', caused by java.lang.NullPointerException

The error does not occur when I stack any other models, only appears with the GLM. Of course I use the same folds for cross-validation.
Some sample code for training the model and the ensemble:
glm_grid <- h2o.grid(algorithm = "glm",
family = 'binomial',
grid_id = "glm_grid",
x = predictors,
y = response,
seed = 1,
fold_column = "fold_assignment",
training_frame = train_h2o,
keep_cross_validation_predictions = TRUE,
hyper_params = list(alpha = seq(0, 1, 0.05)),
lambda_search = TRUE,
search_criteria = search_criteria,
balance_classes = TRUE,
early_stopping = TRUE)
glm <- h2o.getGrid("glm_grid",
sort_by="auc",
decreasing=TRUE)
ensemble <- h2o.stackedEnsemble(x = predictors,
y = response,
training_frame = train_h2o,
model_id = "ens_1",
base_models = glm#model_ids[1:5])

This is a bug, and you can track the progress of the fix here (this should be fixed in the next release, but it might be fixed sooner and available on the nightly releases).
I was going to suggest training the GLMs in a loop or apply function (instead of using h2o.grid()) as a temporary work-around, but unfortunately, the same error happens.

Stanford NER Error: Loading distsim lexicon Failed

In my project. I need to use NER annotation so I used NERDemo.java
It works fine when I create a new project and have only this code, but when I add it to my project I keep getting errors. I have edited the path in my code to the specific location of the classifiers.
I added the Jar files:
This is the code:
String serializedClassifier = "/Users/ha/stanford-ner-2014-10-26/classifiers/english.all.3class.distsim.crf.ser.gz";
String serializedClassifier2 = "/Users/ha/stanford-ner-2014-10-26/classifiers/english.muc.7class.distsim.crf.ser.gz";
if (args.length > 0) {
serializedClassifier = args[0];
}
NERClassifierCombiner classifier = new NERClassifierCombiner(false, false, serializedClassifier, serializedClassifier2);
String fileContents = IOUtils.slurpFile("/Users/ha/NetBeansProjects/StanfordPOSCode/src/stanfordposcode/input.txt");
List<List<CoreLabel>> out = classifier.classify(fileContents);
int i = 0;
for (List<CoreLabel> lcl : out) {
i++;
int j = 0;
for (CoreLabel cl : lcl) {
j++;
System.out.printf("%d:%d: %s%n", i, j,
cl.toShorterString("Text", "CharacterOffsetBegin", "CharacterOffsetEnd", "NamedEntityTag"));
}
}
But I got this error:

You are mixing and matching the code from version 3.4 and the models from version 3.5. I suggest upgrading everything to the latest version.

While update index object value have double quotes throws exception

I am trying to update index using update script, if index object value have double quotes I am getting exception.
Using the following code:
Employee employee = Employee();
employee.setId(16661L);
employee.setEmployeeId(11026L);
employee.setEmployeeName("Ashok"s Kumar");
employee.setEmailId("ashokkumar#yahoo.com");
final StringBuilder updateScript = new StringBuilder("ctx._source.employees.add("
+ employee + ");");
final UpdateRequestBuilder request = CLIENT.prepareUpdate(indexName, String.valueOf("88"), "14344");
final UpdateResponse response = request.setScript(updateScript.toString()).execute().actionGet();
while execute this getting following exception:

Any one have solution for this please?

Please try by replacing
employeeName = employeeName.replace("\"", "\\\"");
