> Key: HBASE-5071
> URL: https://issues.apache.org/jira/browse/HBASE-5071
> Project: HBase
> Issue Type: Bug
> Components: HFile, io
> Affects Versions: 0.90.0
> Reporter: Harsh J
> Labels: hfile
> Fix For: 0.96.0
>
>
> HBASE-3040 introduced this line originally in HFile.Reader#loadFileInfo(...):
> {code}
> int allIndexSize = (int)(this.fileSize - this.trailer.dataIndexOffset -
> FixedFileTrailer.trailerSize());
> {code}
> Which on trunk today, for HFile v1 is:
> {code}
> int sizeToLoadOnOpen = (int) (fileSize - trailer.getLoadOnOpenDataOffset() -
> trailer.getTrailerSize());
> {code}
> This computed (and casted) integer is then used to build an array of the same
> size. But if fileSize is very large (>> Integer.MAX_VALUE), then there's an
> easy chance this can go negative at some point and spew out exceptions such
> as:
> {code}
> java.lang.NegativeArraySizeException

> {code}
> Did we accidentally limit single region sizes this way?
> (Unsure about HFile v2's structure so far, so do not know if v2 has the same
> issue.)
