Cosmin Lehene commented on HBASE-3706:
--------------------------------------
[[email protected]] HDFS-1195 is stale... I'm assuming the same behavior
still applies? Would it make sense to refresh this?
> On node crash (RS+DN), the replication of blocks can up latency

> Project: HBase
> Issue Type: Bug
> Reporter: stack
>
> HDFS is kinda dumb regards rereplication in that if it notices missing
> replicas, its crass in the way it goes about making redress; there is no
> facility for limiting the rate of rereplication (HDFS-1195). We've seen the
> case where hdfs is rereplicating at such a rate after DN crash, it fills the
> network hampering data serving. This issue is about noting this prob. and
> helping out/keeping an eye on HDFS-1195.
