Scan HTable rows for specific column value using HBase shell

I want to scan rows in a HTable from hbase shell where a column family (i.e., Tweet) has a particular value (i.e., user_id).

Now I want to find all rows where tweet:user_id has value test1 as this column has value 'test1'

column=tweet:user_id, timestamp=1339581201187, value=test1

Though I can scan table for a particular using, 

scan 'tweetsTable',{COLUMNS => 'tweet:user_id'}

but I did not find any way to scan a row for a value.

Is it possible to do this via HBase Shell?

I checked this question as well.

Solution

  • It is possible without Hive:

    scan 'filemetadata', 
     { COLUMNS => 'colFam:colQualifier', 
       LIMIT => 10, 
       FILTER => "ValueFilter( =, 'binaryprefix:<someValue.e.g. test1 AsDefinedInQuestion>' )" 
     }

    Note: in order to find all rows that contain test1 as value as specified in the question, use binaryprefix:test1 in the filter (see this answer for more examples)
