------------------------------------
Summary: ACID Compactor, PartialScanTask, MergeFileTask,
ColumnTruncateTask, HCatUtil don't close JobClient (was: ACID: Compactor
doesn't close JobClient)

> When a compaction job is launched, we create a new JobClient everytime we run
> the MR job:
> {code}
> private void launchCompactionJob(JobConf job, Path baseDir, CompactionType
> compactionType,
> StringableList dirsToSearch,
> List<AcidUtils.ParsedDelta> parsedDeltas,
> int curDirNumber, int obsoleteDirNumber,
> HiveConf hiveConf,
> TxnStore txnHandler, long id, String
> jobName) throws IOException {
> job.setBoolean(IS_MAJOR, compactionType == CompactionType.MAJOR);
> if(dirsToSearch == null) {
> dirsToSearch = new StringableList();
> }
> StringableList deltaDirs = new StringableList();
> long minTxn = Long.MAX_VALUE;
> long maxTxn = Long.MIN_VALUE;
> for (AcidUtils.ParsedDelta delta : parsedDeltas) {
> LOG.debug("Adding delta " + delta.getPath() + " to directories to
> search");
> dirsToSearch.add(delta.getPath());
> deltaDirs.add(delta.getPath());
> minTxn = Math.min(minTxn, delta.getMinTransaction());
> maxTxn = Math.max(maxTxn, delta.getMaxTransaction());
> }
> if (baseDir != null) job.set(BASE_DIR, baseDir.toString());
> job.set(DELTA_DIRS, deltaDirs.toString());
> job.set(DIRS_TO_SEARCH, dirsToSearch.toString());
> job.setLong(MIN_TXN, minTxn);
> job.setLong(MAX_TXN, maxTxn);
> if (hiveConf.getBoolVar(HiveConf.ConfVars.HIVE_IN_TEST)) {
> mrJob = job;
> }
> LOG.info("Submitting " + compactionType + " compaction job '" +
> job.getJobName() + "' to " + job.getQueueName() + " queue. " +
> "(current delta dirs count=" + curDirNumber +
> ", obsolete delta dirs count=" + obsoleteDirNumber + ". TxnIdRange[" +
> minTxn + "," + maxTxn + "]");
> RunningJob rj = new JobClient(job).submitJob(job);
> LOG.info("Submitted compaction job '" + job.getJobName() + "' with
> jobID=" + rj.getID() + " compaction ID=" + id);
> txnHandler.setHadoopJobId(rj.getID().toString(), id);
> rj.waitForCompletion();
> if (!rj.isSuccessful()) {
> throw new IOException(compactionType == CompactionType.MAJOR ? "Major"
> : "Minor" +
> " compactor job failed for " + jobName + "! Hadoop JobId: " +
> rj.getID() );
> }
> }
> {code}
> We should close the JobClient to release resources (cached FS objects etc).
