Uma Maheswari commented on PARQUET-196:
---------------------------------------

Can I know the difference between pretty and detailed size?

Gives same results. Code also looks same. 
Is that something like size -pretty means only datablock size and size 
-detailed means completed parquet file size (header+datablocks+footer)?

 

> parquet-tools command to get rowcount & size

> Parquet files contain metadata about rowcount & file size. We should have new 
> commands to get rows count & size.
> These command can be added in parquet-tools:
> 1. rowcount : This should add number of rows in all footers to give total 
> rows in data. 
> 2. size : This should give compresses size in bytes and human readable format 
> too.
> These command helps us to avoid parsing job logs or loading data once again 
> to find number of rows in data. This comes very handy in complex processes, 
> stats generation, QA etc..
