Example 1 with NullScanFileSystem

use of org.apache.hadoop.hive.ql.io.NullScanFileSystem in project hive by apache.

the class RemoteHiveSparkClient method submit.

private SparkJobRef submit(final DriverContext driverContext, final SparkWork sparkWork) throws Exception {
    final Context ctx = driverContext.getCtx();
    final HiveConf hiveConf = (HiveConf) ctx.getConf();
    refreshLocalResources(sparkWork, hiveConf);
    final JobConf jobConf = new JobConf(hiveConf);
    // update the credential provider location in the jobConf
    HiveConfUtil.updateJobCredentialProviders(jobConf);
    // Create temporary scratch dir
    final Path emptyScratchDir = ctx.getMRTmpPath();
    FileSystem fs = emptyScratchDir.getFileSystem(jobConf);
    fs.mkdirs(emptyScratchDir);
    // make sure NullScanFileSystem can be loaded - HIVE-18442
    jobConf.set("fs." + NullScanFileSystem.getBaseScheme() + ".impl", NullScanFileSystem.class.getCanonicalName());
    byte[] jobConfBytes = KryoSerializer.serializeJobConf(jobConf);
    byte[] scratchDirBytes = KryoSerializer.serialize(emptyScratchDir);
    byte[] sparkWorkBytes = KryoSerializer.serialize(sparkWork);
    JobStatusJob job = new JobStatusJob(jobConfBytes, scratchDirBytes, sparkWorkBytes);
    if (driverContext.isShutdown()) {
        throw new HiveException("Operation is cancelled.");
    }
    JobHandle<Serializable> jobHandle = remoteClient.submit(job);
    RemoteSparkJobStatus sparkJobStatus = new RemoteSparkJobStatus(remoteClient, jobHandle, sparkClientTimtout);
