gaojinchao commented on HBASE-4577:
-----------------------------------
All have the same block structure, I think storefileUncompressedSizeMB means
sum of all uncompressedSizeWithHeader
Here are some comments
/** Total uncompressed bytes, maybe calculate a compression ratio later. */
protected long totalUncompressedBytes = 0;
I try to make a patch. Can you review whether it makes sense ?
> Region server reports storefileSizeMB bigger than storefileUncompressedSizeMB

> Minor issue while looking at the RS metrics:
> bq. numberOfStorefiles=8, storefileUncompressedSizeMB=2418,
> storefileSizeMB=2420, compressionRatio=1.0008
> I guess there's a truncation somewhere when it's adding the numbers up.
> FWIW there's no compression on that table.
