> Key: HDFS-3411
> URL: https://issues.apache.org/jira/browse/HDFS-3411
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: balancer
> Affects Versions: 0.23.0
> Reporter: Ashish Singhi
>
> Scaenario:
> replication set to 1.
> 1. Start 1NN and IDN
> 2. pump 1GB of data.
> 3. Start one more DN
> 4. Run balancer with threshold 1.
> Now DN1 is added into aboveAvgUtilizedDatanodes and DN2 into
> belowAvgUtilizedDatanodes. Hence overLoadedBytes and underLoadedBytes will be
> equal to 0. Resulting in bytesLeftToMove equal to 0. Thus balancer will exit
> without balancing the blocks.
