> The storage memory displayed on spark Application UI is incorrect.
> ------------------------------------------------------------------
>
> Key: SPARK-25696
> URL: https://issues.apache.org/jira/browse/SPARK-25696
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.3.2
> Reporter: hantiantian
> Priority: Major
>
> In the reported heartbeat information, the unit of the memory data is bytes,
> which is converted by the formatBytes() function in the utils.js file before
> being displayed in the interface. The base of the unit conversion in the
> formatBytes function is 1000, which should be 1024.
> function formatBytes(bytes, type) {
> if (type !== 'display') return bytes;
> if (bytes == 0) return '0.0 B';
> var k = 1000;
> var dm = 1;
> var sizes = ['B', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'];
> var i = Math.floor(Math.log(bytes) / Math.log(k)); return
> parseFloat((bytes / Math.pow(k, i)).toFixed(dm)) + ' ' + sizes[i];
> }
