> Yes guys. We observed such problems.
> They will be common for 0.18.2 and 0.19.0 exactly as you
> described it when data-nodes become unstable.
> There were several issues, please take a look
> HADOOP-4997 workaround for tmp file handling on DataNodes
> HADOOP-4663 - links to other related
> HADOOP-4810 Data lost at cluster startup
> HADOOP-4702 Failed block replication leaves an incomplete block

> 0.19.1 should be the same.
