-----------------------------
Summary: Data corruption can cause
SerializationUtils.readRemainingLongs() function hang
Key: HIVE-18142
URL: https://issues.apache.org/jira/browse/HIVE-18142
Project: Hive
Issue Type: Bug
Affects Versions: 1.0.0
Reporter: Dustin
Fix For: 2.1.0, 2.0.1
Similar to the SerializationUtils.readLongBE() function reported in
[HIVE-13255|https://issues.apache.org/jira/browse/HIVE-13255], when Instream is
corrupted, the following loop can become infinite, too.
{code:java}
private void readRemainingLongs(long[] buffer, int offset, InStream input,
int remainder,
int numBytes) throws IOException {
final int toRead = remainder * numBytes;
// bulk read to buffer
int bytesRead = input.read(readBuffer, 0, toRead);
while (bytesRead != toRead) {
bytesRead += input.read(readBuffer, bytesRead, toRead - bytesRead);
}
...
}
{code}
