    try {
        openTransaction();
        funcName = HiveStringUtils.normalizeIdentifier(funcName);

            throw new InvalidObjectException("new function is invalid");
        }
        MFunction oldf = getMFunction(dbName, funcName);
        if (oldf == null) {
            throw new MetaException("function " + funcName + " doesn't exist");
        }
        // For now only alter name, owner, class name, type
        oldf.setFunctionName(HiveStringUtils.normalizeIdentifier(newf.getFunctionName()));
        oldf.setDatabase(newf.getDatabase());
        oldf.setOwnerName(newf.getOwnerName());

        // commit the changes
        success = commitTransaction();
    } finally {
        if (!success) {
            rollbackTransaction();
        }
    }
}

Example 2 with MFunction

    try {
        openTransaction();
        Query query = pm.newQuery(MFunction.class);
        List<MFunction> allFunctions = (List<MFunction>) query.execute();
        pm.retrieveAll(allFunctions);
        commited = commitTransaction();
        return convertToFunctions(allFunctions);
    } finally {
        if (!commited) {
            rollbackTransaction();
        }
    }
}

    if (func == null) {
        return null;
    }
    MDatabase mdb = null;
    try {
        mdb = getMDatabase(func.getDbName());
    } catch (NoSuchObjectException e) {
        LOG.error(StringUtils.stringifyException(e));
        throw new InvalidObjectException("Database " + func.getDbName() + " doesn't exist.");
    }
    MFunction mfunc = new MFunction(func.getFunctionName(), mdb, func.getClassName(), func.getOwnerName(), func.getOwnerType().name(), func.getCreateTime(), func.getFunctionType().getValue(), convertToMResourceUriList(func.getResourceUris()));
    return mfunc;
}

    boolean success = false;
    try {
        openTransaction();
        MFunction mfunc = getMFunction(dbName, funcName);
        pm.retrieve(mfunc);
        if (mfunc != null) {
            // TODO: When function privileges are implemented, they should be deleted here.
            pm.deletePersistentAll(mfunc);
        }
        success = commitTransaction();
    } finally {
