Guangxu Cheng commented on HBASE-18001:
---------------------------------------
bq.Are users still able to pass on the size of cache to scan?
{code}
params = {
'INTERVAL' => 1000,
'CACHE' => 10
}.merge(params)
scan = table._hash_to_scan(params)
{code}
{code}
- count = table._count_internal(params['INTERVAL'].to_i,
params['CACHE'].to_i) do |cnt, row|
+ count = table._count_internal(params['INTERVAL'].to_i, scan) do |cnt,
row|
{code}
sure, parameter CACHE will be set to the scan by _hash_to_scan(params) in
couter.rb
> Extend the "count" shell command to support specified conditions

> shell command "count" can only count the number of rows in a table.
> And, it could not count the number of the specified conditions.
> Can we allow users to specified conditions like command "scan"?
> In that case, we can count the number of rows under any conditions.
