Subject about select count(*) from table
Date Sat, 09 Jan 2016 07:03:24 GMT

Hi

 Use cdh hbase 1.0.0 and drill 1.4.0 , the table is  one family and one col . If value of
col  is longer string just like this format : a1|a2|a3|a4...................|a1000, 
 
 Then   if i insert into hbase 1000000 rows ,when use select count(*) from `tablename` , the
result is more less 1000000 ,just like 5000 rows

But if value of col is short just like this format: a1|a2 , the result is correctly.

 Is bug ? or my query is incorrctly  ? or drill is not support largest  column of hbase ?
