Xiao Chen updated HDFS-12603:
-----------------------------
    Attachment: HDFS-12603.branch-2.01.patch

Hm, seems adding toString to FSEditLog itself solved it. I think we should do this for the trunk patch too, will attach one shortly.

Just curious, how did you pin this down to toString initially?

> HDFS-7964 added support for async edit logging. Based on further discussion in that JIRA, we think it's safe to turn this on by default for better out-of-the-box performance.
