Wang Xu commented on HADOOP-5729:
---------------------------------
I modified the patch to call processIOError() instead of exit directly if no
editStream were opened.
> FSEditLog.open should stop going on if cannot open any directory

> Components: dfs
> Affects Versions: 0.19.1
> Environment: CentOS 5.2, jdk 1.6, hadoop 0.19.1
> Reporter: Wang Xu

> Original Estimate: 1h

> FSEditLog.open will be invoked when SecondaryNameNode doCheckPoint,
> If no dir is opened successfully, it only prints some WARN messages in log,
> and goes on running.
> However, it causes the editStreams becomes empty and cannot by synced
> in. And if editStreams were decreased to 0 when exceptions occured during
> logsync, NameNode would print FATAL log message and halt itself. Hence,
> we think it should also stopped itself at that time.
