> case BEELINE:
> String tmpHqlPath = null;
> StringBuilder hql = new StringBuilder();
> try {
> tmpHqlPath = "/tmp/" + System.currentTimeMillis() + ".hql";
> for (String statement : statements) {
> hql.append(statement);
> hql.append("\n");

> String createFileCmd =
> String.format(CREATE_HQL_TMP_FILE_TEMPLATE, tmpHqlPath, hql);
> buf.append(createFileCmd);
> buf.append("\n");
> buf.append(beelineShell);
> buf.append(" ");
> buf.append(beelineParams);
> buf.append(parseProps());
> buf.append(" -f ");
> buf.append(tmpHqlPath);
> buf.append(";ret_code=$?;rm -f ");
> buf.append(tmpHqlPath);
> buf.append(";exit $ret_code");
> } finally {
> if (tmpHqlPath != null && logger.isDebugEnabled()) {
> logger.debug("The SQL to execute in beeline: \n" + hql);

> A temp hql file will be created when creating flat table, the file name is
> the current time stamp. But if two jobs triggered with same time, there will
> be only one file, and jobs may be failed
