Binglin Chang updated HDFS-7471:
--------------------------------
Attachment: HDFS-7471.001.patch
Simple work around to increase expire interval.
After investigate the code, I suspect the current countVersion logic may have
race conditions, maybe someone more familiar with the code can provide a better
fix.
