Mismatch in number of bytes already moved and number of bytes being moved in
balancer report
--------------------------------------------------------------------------------------------
Key: HDFS-3295
URL: https://issues.apache.org/jira/browse/HDFS-3295
Project: Hadoop HDFS
Issue Type: Bug
Components: balancer
Affects Versions: 0.23.0
Reporter: J.Andreina
Fix For: 0.24.0
Scenario:
Replication factor =
1,fs.defaultFS=hdfs://namenodeip:port,dfs.namenode.rpc-address=namenodeip:port.
step 1: started DN1.Pumped 4.67GB of data
step 2: started DN2.
step 3: issued the balancer cmd(./start-balancer.sh -threshold 1)
Totally 848.41 MB has been moved to 2DN and took 4 iterations to move the
blocks to 2DN.
But in balancer output in all the iterations the number of bytes already moved
is alway 0KB and there is mismatch in the Bytes being moved with the bytes
left to move
Balancer output for 2nd Iteration

151.18 MB{noformat}
In the above balancer output
•Bytes already moved is 0KB
• In 3 rd iterarion Bytes left to move is 223.84 MB but Bytes being moved is
151.18 MB . So in next iteration the bytes left to move should be 223.84 MB -
151.18 MB
