Karthik Palanisamy updated HBASE-23115:
---------------------------------------
Description:
StoreFileSize and MemstoreSize usually returned in MBs (link1, link2) but few
jsp pages contain inaccurate unit. The reason is table.jsp (link3) use
org.apache.hadoop.util.StringUtils.byteDesc(long len), this will perform
longtostring conversion and returns its unit(B, KB, MB, GB, TB, PB) based on
length. The concern here (link4) is computation (ByteVal/1024/1024) will output
always lesser than 1 for store contains few bytes or few kbs. Also, typecast
will not round up to its nearest value.
I think the best option is changing unit in table.jsp instead of changing code,
otherwise we may end up doing many refactors from getMemStoreSizeMB,
setMemStoreSizeMB, hasMemStoreSizeMB, getStorefileSizeMB, setStorefileSizeMB,..
Please find the attachment, a simple example is posted.
