[jira] [Commented] (HIVE-19393) NonSyncDataInputBuffer.skipBytes
hangs when the file is corrupted
[ https://issues.apache.org/jira/browse/HIVE-19393?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16462977#comment-16462977 ]
Sergey Shelukhin commented on HIVE-19393:
-----------------------------------------
Shouldn't "(skip = in.skip(count - skipped)) != 0" prevent it?

> 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
> Priority: Minor
>
> 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}
