HBase篇--HBase操作Api和Java操作Hbase相关Api

一.前述。

Hbase shell启动命令窗口，然后再Hbase shell中对应的api命令如下。

二.说明

Hbase shell中删除键是空格+Ctrl键。

三.代码

1.封装所有的API

 解析：

1.

String rowkey = pnum + "_" + (Long.MAX_VALUE-sdf.parse(datestr).getTime());//默认Hbase是按照row_key的字典升序排列，此处降序。时间戳越来越大，则此数越来越小，达到按照时间降序的结果。

2.过滤器介绍

FilterList代表一个过滤器列表
        FilterList.Operator.MUST_PASS_ALL --> 取交集 相当一and操作
        FilterList.Operator.MUST_PASS_ONE --> 取并集 相当于or 操作
        FilterList list = new FilterList(FilterList.Operator.MUST_PASS_ONE);
        2、SingleColumnValueFilter 列值过滤器
        ColumnPrefixFilter用于指定列名前缀值相等
        MultipleColumnPrefixFilter和ColumnPrefixFilter行为差不多，但可以指定多个前缀。
        QualifierFilter是基于列名的过滤器。
        2、RowFilter 行过滤器
        RegexStringComparator是支持正则表达式的比较器。
        SubstringComparator用于检测一个子串是否存在于值中，大小写不敏感。
