修改oozie action node name的长度限制

在使用oozie的过程中，可能会遇到如下问题：

E0724: Invalid node name, name [your action node name] must be 50 chars or less

可是去mysql里查看表结构，发现WF_ACTIONS表的name字段长度是varchar(255)，于是去查看源代码，发现在core包里的ParamChecker类里有这样一个方法被LiteWorkflowAppParser类调用了

    private static final int MAX_NODE_NAME_LEN = 50;    /**     * Check that the given string is a valid action name [a-zA-Z_][0-9a-zA-Z_\-]* and not longer than 50 chars.     *     * @param actionName string to validate is a token.     * @return the given string.     */    public static String validateActionName(String actionName) {        ParamChecker.notEmpty(actionName, "action name");        if (actionName.length() > MAX_NODE_NAME_LEN) {            throw new IllegalArgumentException(XLog.format("name [{0}] must be {1} chars or less", actionName,                                                           MAX_NODE_NAME_LEN));        }        char c = actionName.charAt(0);        if (!(c >= 'A' && c <= 'Z') && !(c >= 'a' && c <= 'z') && !(c == '_')) {            throw new IllegalArgumentException(XLog.format("name [{0}], must start with [A-Za-z_]", actionName));        }        for (int i = 1; i < actionName.length(); i++) {            c = actionName.charAt(i);            if (!(c >= '0' && c <= '9') && !(c >= 'A' && c <= 'Z') && !(c >= 'a' && c <= 'z')                    && !(c == '_' || c == '-')) {                throw new IllegalArgumentException(XLog.format("name [{0}] must be [A-Za-z_][0-9A-Za-z_]*", actionName));            }        }        return actionName;    }

这里的MAX_NODE_NAME_LEN被写死了50，于是修改成100重新编译打包，打包时最好跳过测试，mvn install -Dmaven.test.skip=true

打好包之后把 oozie-core-xxx.jar包拷到oozie的安装目录覆盖掉原jar包，重启oozie即可
