Hi,

I am learning different tools in Hadoop and getting confused with the same kind of command, but they do some different activity. Can anyone explain the use of Count keyword in HBase?

Hey,

An aggregate function that returns the number of rows, or the number of non-NULL rows. Count interval may be optionally specified.

Syntax:

COUNT([DISTINCT | ALL] expression) [OVER (analytic_clause)]

Depending on the argument, COUNT() considers rows that meet certain conditions.
