Hong Tang commented on MAPREDUCE-1925:
--------------------------------------
PossiblyDecompressedInputStream.close() seems to be wrong. it should close
coreInputStream before returning back the decompressor.
The following is also problematic:
{code}
BufferedInputStream bis = new BufferedInputStream(inputLogStream);
bis.mark(10000);
Hadoop20JHParser parser = new Hadoop20JHParser(bis);
{code}
The default buffer size is 8K, so mark a position with a read-ahead limit of
10000 characters could fail if the underlying stream does too much read ahead.
