-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Chandra!
Replication is done according to priority (e.g. where only 1 block out of 3 remains is higher priority than when only 2 out of 3 remain). Every time a DN heartbeats into the NN, it *may* be assigned some replication work according to some criteria. See dfs.namenode.replication.work.multiplier.per.iteration . The list of blocks that need to be replicated is calculated once every dfs.namenode.replication.interval HTH Ravi On 05/11/14 07:20, chandra kant wrote: > Hi, > > Some of my blocks are under replicated.
