Description

In order to avoid the pressure of massive queries on hbase，htable read quota is necessary。Through a new configuration “kylin.hbase.htable-quota”，we can control the read quota when the htable created。The default value of this conf is -1，means will not limit queries。You can set it to any intger greater than 0 as needed。
