Different size of datasource in Coordinator and Hadoop DeepStorage

Hi everyone,

I ingested log data to druid (datasource name: XYZ) and configurated Hadoop as a deep storage. But, the problem is that: size of the ingested datasource different in deep storage and Coordinator

In my check, the size of XYZ in deep storage is 1.3GB (command hadoop: hdfs dfs -du -s -h /druid/segments/XYZ) and the size of it’s presentation in Coordinator is 2.95GB

Can anyone help me to explain between two size of datasource number, which is true ?
