Scott Chen commented on HDFS-983:
---------------------------------
Just discussed with Rodrigo and Dmytro. The filename may be decoded so it loses
all the null characters. So this problem may still related to HADOOP-6522.
> NameNode transaction log corruption with bad filename

> The SecondaryNamenode is unable to create checkpoints. The stack trace is
> attached. This is the second time we have seen this issue. Both these
> occurances happened with unprintable characters in the filename. I am
> wondering if there is an String-UTF8 encoding problem.
