  • HBase shell查询指定范围行键

    最简单的方法就用SCAN加参数STARTROW和ENDROW

    hbase(main):024:0> scan 'score',{STARTROW=>'0005',ENDROW=>'0008'}

     输出结果:

    ROW COLUMN+CELL 
    0005 column=course:Operating System, time
    0005 column=grade:order2, timestamp=98, v
    0006 column=course:math, timestamp=160533
    0006 column=grade:order3, timestamp=16053
    0007 column=course:math, timestamp=160533
    0007 column=grade:order4, timestamp=92, v
    3 row(s) in 0.0330 seconds

    或者参数和过滤器混用

    hbase(main):021:0> scan 'score',{STARTROW=>'0005',FILTER=>"RowFilter(<=,'binary:0007')"}

     输出结果:

    ROW COLUMN+CELL 
    0005 column=course:Operating System, timestamp=1605339202987, value=91
    0005 column=grade:order2, timestamp=98, value=course:math
    0006 column=course:math, timestamp=1605339211226, value=95
    0006 column=grade:order3, timestamp=1605339603983, value=No.4
    0007 column=course:math, timestamp=1605339216074, value=92
    0007 column=grade:order4, timestamp=92, value=course:Java
    3 row(s) in 0.0430 seconds

    hbase(main):022:0> scan 'score',{ENDROW=>'0008',FILTER=>"RowFilter(>=,'binary:0005')"}

    输出结果:
    ROW COLUMN+CELL
    0005 column=course:Operating System, timestamp=1605339202987, value=91
    0005 column=grade:order2, timestamp=98, value=course:math
    0006 column=course:math, timestamp=1605339211226, value=95
    0006 column=grade:order3, timestamp=1605339603983, value=No.4
    0007 column=course:math, timestamp=1605339216074, value=92
    0007 column=grade:order4, timestamp=92, value=course:Java
    3 row(s) in 0.0430 seconds

    两个过滤器的话无法实现,会单执行后面的过滤器

    测试输入:

    hbase(main):023:0> scan 'score',{FILTER=>"RowFilter(>=,'binary:0005')",FILTER=>"RowFilter(<=,'binary:0007')"}

    输出结果:
    ROW COLUMN+CELL
    0001 column=course:math, timestamp=1605339168973, value=99
    0001 column=grade:order1, timestamp=99, value=course:math
    00010 column=course:Java, timestamp=1605339236065, value=97
    0002 column=course:english, timestamp=160
    0002 column=grade:order1, timestamp=96, v
    0003 column=course:english, timestamp=160
    0003 column=grade:order1, timestamp=93, v
    0004 column=course:Java, timestamp=160533
    0004 column=course:math, timestamp=160533
    0004 column=grade:order1, timestamp=95, v
    0005 column=course:Operating System, time
    0005 column=grade:order2, timestamp=98, v
    0006 column=course:math, timestamp=160533
    0006 column=grade:order3, timestamp=16053
    0007 column=course:math, timestamp=160533
    0007 column=grade:order4, timestamp=92, v
    8 row(s) in 0.0280 seconds
