John Doe updated HADOOP-15088:
------------------------------
Description:
When a file is corrupted, the skip function can return 0, causing an infinite
loop.
Here is the code:
{code:java}
private boolean slowReadUntilMatch(Pattern markPattern, boolean includePat,
DataOutputBuffer outBufOrNull) throws
IOException {
...
for (long skiplen = endPos; skiplen > 0; ) {
skiplen -= bin_.skip(skiplen);
}
...
}
{code}
