[jira] [Created] (HIVE-19393) NonSyncDataInputBuffer.skipBytes
hangs when the file is corrupted
John Doe created HIVE-19393:
-------------------------------
Summary: NonSyncDataInputBuffer.skipBytes hangs when the file is corrupted
Key: HIVE-19393
URL: https://issues.apache.org/jira/browse/HIVE-19393
Project: Hive
Issue Type: Bug
Components: SQL
Affects Versions: 1.0.0
Reporter: John Doe
When an InputStream is corrupted, the InputStream.skip can return 0, causing the while loop in NonSyncDataInputBuffer.skipBytes become infinite.
{code:java}
public final int skipBytes(int count) throws IOException {
int skipped = 0;
long skip;
while (skipped < count && (skip = in.skip(count - skipped)) != 0) {
skipped += skip;
}
if (skipped < 0) {
throw new EOFException();
}
return skipped;
}
{code}
