> Key: HBASE-28059
> URL: https://issues.apache.org/jira/browse/HBASE-28059
> Project: HBase
> Issue Type: Improvement
> Components: Admin
> Affects Versions: 2.5.5
> Reporter: Charles Connell
> Assignee: Charles Connell
> Priority: Major
> Fix For: 2.6.0, 2.4.18, 2.5.6

>
> When I run a snippet of code like this:
> {code:java}
> Map<byte[], RegionLoad> regionLoadMap = admin
> .getClusterStatus()
> .getLoad(
> ServerName.parseServerName(
> "my-server.my-company.net,60020,1693513660506"
> )
> )
> .getRegionsLoad();
> for (byte[] startKey : regionLoadMap.keySet()) {
> RegionLoad regionLoad = regionLoadMap.get(startKey);
> LOG.info("Region {}: {}", Bytes.toStringBinary(startKey), regionLoad);
> } {code}
> I get logs like this:
> {noformat}
> Region <redacted-table-name>,<redacted row
> key>,1659484033280.2b89407a1223720344bed425bf3c29b0.: numberOfStores=1,
> numberOfStorefiles=3, storeRefCount=0, storefileUncompressedSizeMB=17998848,
> lastMajorCompactionTimestamp=1693211464712, storefileSizeMB=5895,
> compressionRatio=0.0003, memstoreSizeMB=1, readRequestsCount=118899553,
> writeRequestsCount=731192, rootIndexSizeKB=9, totalStaticIndexSizeKB=10413,
> totalStaticBloomSizeKB=6592, totalCompactingKVs=0, currentCompactedKVs=0,
> compactionProgressPct=NaN, completeSequenceId=78093096,
> dataLocality=1.0{noformat}
> The {{storefileUncompressedSizeMB}} is vastly larger than the
> {{{}storefileSizeMB{}}}, so much more that it's not believable. I checked the
> store files in question in this instance. Adding up the uncompressed size
> reported in the HFile trailers sums to 5895 MiB, exactly 1024 times less than
> the reported 17998848.
> The reason for the misreporting is that
> {{RegionLoad#getStoreUncompressedSizeMB()}} converts the value from a
> {{Size}} object wrong.
