Examples with ResourceDownloader org.apache.hadoop.hive.ql.util.ResourceDownloader used on opensource projects

Example 1 with ResourceDownloader

use of org.apache.hadoop.hive.ql.util.ResourceDownloader in project hive by apache.

the class LlapServiceDriver method downloadPermanentFunctions.

private Set<String> downloadPermanentFunctions(Configuration conf, Path udfDir) throws HiveException, URISyntaxException, IOException {
    Map<String, String> udfs = new HashMap<String, String>();
    HiveConf hiveConf = new HiveConf();
    // disable expensive operations on the metastore
    hiveConf.setBoolVar(HiveConf.ConfVars.METASTORE_INIT_METADATA_COUNT_ENABLED, false);
    hiveConf.setBoolVar(HiveConf.ConfVars.METASTORE_METRICS, false);
    // performance problem: ObjectStore does its own new HiveConf()
    Hive hive = Hive.getWithFastCheck(hiveConf, false);
    ResourceDownloader resourceDownloader = new ResourceDownloader(conf, udfDir.toUri().normalize().getPath());
    List<Function> fns = hive.getAllFunctions();
    Set<URI> srcUris = new HashSet<>();
    for (Function fn : fns) {
        String fqfn = fn.getDbName() + "." + fn.getFunctionName();
        if (udfs.containsKey(fn.getClassName())) {
            LOG.warn("Duplicate function names found for " + fn.getClassName() + " with " + fqfn + " and " + udfs.get(fn.getClassName()));
        }
        udfs.put(fn.getClassName(), fqfn);
        List<ResourceUri> resources = fn.getResourceUris();
        if (resources == null || resources.isEmpty()) {
            LOG.warn("Missing resources for " + fqfn);
            continue;
        }
        for (ResourceUri resource : resources) {
            srcUris.add(ResourceDownloader.createURI(resource.getUri()));
        }
    }
    for (URI srcUri : srcUris) {
        List<URI> localUris = resourceDownloader.downloadExternal(srcUri, null, false);
        for (URI dst : localUris) {
            LOG.warn("Downloaded " + dst + " from " + srcUri);
        }
    }
    return udfs.keySet();
}

Example 2 with ResourceDownloader

use of org.apache.hadoop.hive.ql.util.ResourceDownloader in project hive by apache.

the class FunctionLocalizer method init.

public void init() throws IOException {
    if (localDir.exists()) {
        // TODO: We don't want some random jars of unknown provenance sitting around. Or do we care?
        // Ideally, we should try to reuse jars and verify using some checksum.
        FileUtils.deleteDirectory(localDir);
    }
    this.resourceDownloader = new ResourceDownloader(conf, localDir.getAbsolutePath());
    workThread.start();
