> It is observed that, even though *metricslimit* is set to 1500, maximum
> number of metrics values retrieved is 1000.
> This is due to, while creating EntityTable, metrics column family max version
> is specified as 1000 which is hardcoded in
> {{EntityTable#DEFAULT_METRICS_MAX_VERSIONS}}. So, HBase will return max
> version with following {{MIN(cf max version , user provided max version)}}.
> This behavior is contradicting the documentation which claims that
> {code}
> metricslimit - If specified, defines the number of metrics to return.
> Considered only if fields contains METRICS/ALL or metricstoretrieve is
> specified. Ignored otherwise. The maximum possible value for metricslimit can
> be maximum value of Integer. If it is not specified or has a value less than
> 1, and metrics have to be retrieved, then metricslimit will be considered as
> 1 i.e. latest single value of metric(s) will be returned.
