> Key: HBASE-25674

> Project: HBase
> Issue Type: Bug
> Components: Client

>
> The RegionInfo class uses
> {code:java}
> DataInputStream.read(byte[lengthOfPBMagic])
> {code}
> to read the protobuf magic marker from the beginning of the stream.
> The code in RegionInfo assumes that the passed byte buffer will be filled,
> but the DataInputStream class only guarantees that it will read at most
> lengthOfPBMagic bytes.
> This sometimes causes errors stating that region info file could not be
> parsed.
> The fix is to simply issue multiple read calls until lengthOfPBMagic bytes
> have been read.
